CHAPTER IV. Commercial Duck Farming--Management of the Breeding Stock

Age of Breeders. On most large commercial duck plants the entire breeding stock is renewed each year. In other words, the breeders are kept only through their first laying season. This makes it necessary to select from the young stock reared and save for breeders as many head as it is desired to carry for the coming year. This practice is used for the reason that ducks lay best during their first year. Therefore, since it is desired to keep up the maximum egg production in order to raise as many market ducks as possible, young breeders are considered better. Some raisers, however, keep a part of their breeding ducks for two years and occasionally for 3 or even 4 years but this is not the usual practice. Recent comparison made between young and two year old ducks as breeders would seem to indicate that ducklings hatched from the eggs of the latter live a little better.


Distinguishing Young from Old Ducks. In this connection it is of interest to know how young ducks can be readily distinguished from the older birds. The young ducks have bright yellow legs and bills while the old ducks after a period of laying, lose a considerable amount of the yellow from these sections. In addition, soon after the ducks begin to lay, their bills as a rule will begin to be streaked with black. Young ducks can also be told from the old ducks by feeling of the end of the breast bone which runs to a point at the abdomen. In the older ducks this is hard while in the young ducks it is gristly and bends easily. The windpipe of an old duck is hard and rather difficult to compress or dent while in the young duck it is softer and easily dented.


Selection of Breeding Ducks. The breeders are usually selected from the ducklings which reach market age from the last week in June through July. As these lots become ready for market and are driven into the pens to be slaughtered each duck is handled and any especially good birds which the proprietor thinks will make good breeders are thrown out at this time.

In making selection of breeders those are chosen which are healthy and thrifty and which have good wide, long and deep bodies. Ducks with crooked wings, crooked tails, hump backs or paddle legs are rejected for this purpose. After the young ducks for breeders are selected they are put in a yard or fattening pen until the number which the owner expects to keep is complete. These young breeders generally begin to moult soon after they are selected and from this time on they are fed whole corn and plenty of green feed until it is time to begin feeding the laying ration. Some of the breeding ducks will usually begin to lay about December 1 although they will not lay heavily at that time. The laying ration described later should be begun about that time or a couple of weeks earlier.


Number of Females to a Drake. As a rule on commercial duck farms the birds are mated in the proportion of about one drake to seven ducks. This proportion will vary to some extent under different methods of management and weather conditions and may run all the way from 1 to 5 to 1 to 8. The smaller number of drakes should be used late in the season while the larger number will give better fertility early in the breeding season.

Since the drakes do not fight seriously, flock matings can be made. Better results will be obtained from smaller flocks than from large flocks and there will also be less cracked eggs and less very dirty eggs from the smaller flocks. Before the ducks are let out in the morning there is a tendency for them to run back and forth through the pens, and in this way they tramp over many of the eggs which are laid anywhere about the floor. The larger the flock the more cracked and dirty eggs will result. While the drakes do not fight each other they do at times injure and kill the ducks to some extent when three or four drakes may chase one duck. In this way they may injure the ducks' backs and often pick their eyes and necks. Whenever a duck is found which is injured she should be removed from the flock. Difficulty of this sort is most prevalent about the 1st of March. If the trouble gets very bad it can be stopped to some extent by cutting back the upper bills of the drakes about one-fourth of an inch with a tinsnip or by reducing the proportion of drakes.


Securing Breeding Drakes. It is common practice on duck plants to avoid inbreeding by securing drakes from some other flock each year. This is usually accomplished by buying the drakes outright from some neighboring duck farmer. It may also be accomplished by purchasing a few eggs for hatching in order to secure new blood. In any particular community there is a tendency for the duck farmers to trade breeding drakes among themselves for a period of years with the result that they all have much the same blood and not a great deal of benefit is obtained from securing the drakes from some neighbor's flock. It is undoubtedly good practice to go farther afield occasionally for a supply of breeding drakes. In purchasing stock for new blood be sure that it is as good as the home stock and better if it can be found. It will do no good to purchase and use inferior stock and may do much harm.

 


Houses and Yards for Breeders


The breeding flocks are usually confined to breeding yards. The size of these yards depends upon the size of the breeding flock but large yards are not required. A yard for 200 breeders is not as a rule larger than 100 by 200 feet including the water part of the yard. Houses and yards should be located on sand if possible as this is easier to keep clean and therefore keeps the birds in better condition. Occasional flocks of breeding ducks are allowed their liberty but this is not common practice nor is it good practice unless the surroundings are clean and the ducks do not have access to stagnant mud or refuse in which they can work. If ducks work too much in this kind of material they will eat more or less of it which injures the eggs for hatching purposes.

Many different styles of houses are used for breeders, some of which are decidedly more elaborate than is necessary. A very satisfactory economical house is one 20 feet deep, 7 feet high in front and 4 feet at back, with a shed roof. This can be constructed of tongue and groove material or may be made of unmatched stuff and covered with paper. A house of this proportion makes a good light house and it can be carried in length according to the size of the flock. For a breeding unit of 200 ducks, which is a good unit to use, a house 20 feet deep and 30 to 40 feet long is suitable. No floor is used in the house but it should be well filled up with dirt so that the water will not come in.

One or more good sized openings are left in the front of the breeding house for ventilation, or windows may be placed in the front which can be used for this purpose. Good ventilation is necessary. Additional ventilation is secured from the doors. If the weather is mild the doors are left partly open, if cold they are nearly closed, while when the weather is hot they are left entirely open. A good scheme is to use a sort of Dutch door so that the bottom or top half can be opened independently. In this way the top part of the doors can be left open so as to let in the sunlight and still keep the ducks in the house or the top may be left closed and the bottom opened so as to allow the ducks to go in or out and still cut down the amount of ventilation. When the weather is warm the doors may be left entirely open except for a board 18 inches to 2 feet wide inserted in the bottom of the door when it is desired to keep the ducks in.

Shade is essential for the breeders and if not provided naturally by trees must be supplied by means of artificial shelters.


Bedding and Cleaning the Breeding Houses. Usually straw, meadow hay, or swale hay is used for bedding. Shavings make good material for this purpose if they do not contain too much sawdust. The principal objection to shavings is that it takes longer to bed with them. Often a few joists are laid at the back of the house on which to pile bales of straw or other bedding so that it will be kept dry and will serve as an emergency supply available for bedding the house in stormy days. The houses should be bedded fairly often in order to keep the floors clean and dry and so as not to allow the ducks' feet to get cold. The frequency with which bedding is necessary will depend upon the weather. In winter it may at times be necessary to bed every day. In May it may be necessary only twice a week and still later in the season only once a week. In wet weather the ducks track in lots of mud and water and frequent bedding helps to keep the eggs clean. The houses are cleaned out only once a year and this is usually done after the ducks have stopped laying. To clean out the houses while the ducks are laying would disturb them and tend to stop their egg production.


Cleaning the Breeding Yards. The yards should be cleaned whenever they need it, that is, whenever they begin to get sloppy or sticky. It is a matter of judgment to decide when this is necessary. The character of the soil influences this, as sandy yards absorb the droppings better and do not need cleaning as frequently as heavier soils. In the yards for the breeding ducks, or the water yards, this will as a rule not be over 2 or 3 times a season. In dry weather cleaning is accomplished by sweeping the yards with a broom. In wet weather the droppings spread over the yard and are packed down by the ducks' feet until they form a layer of putty-like material which cannot be swept off but is scraped off by means of a hoe.


Water Yards for Breeders. Formerly it was the consensus of opinion that breeders needed water in which they could swim in order to keep in good breeding condition and to give the best results in fertility of the eggs. At present it is not considered necessary to have sufficient water to permit swimming although many breeders prefer to do this and feel that they get better results from it. However, breeding ducks have been and are being kept successfully in dry yards where water is supplied to them simply in an amount sufficient to allow them to drink and to clean themselves. Where water yards are provided this should not be on stagnant water but there should be some circulation of the water so as to keep it clean and fresh. Where the lay of the land is such that it is not possible to run all the yards down to a stream for this purpose it is sometimes possible to dig a canal or ditch from the stream to the yards so as to allow the ducks access to the water. Where the yards can extend into the water it saves a great deal of labor or considerable expense in equipment as it is not then necessary to provide the ducks with drinking water by means of some artificial arrangement such as a concrete gutter or ditch extending through the yards or by means of artificial ponds.

If the water yards used freeze over in winter it is necessary to cut holes in the ice so that the ducks can get water for drinking purposes. Sometimes the ducks will go into these water holes and after getting their plumage wet will come out and sit down in the yard and freeze fast to the ground. During such weather conditions it is necessary to make the rounds of the yards frequently and to loosen any ducks that have frozen fast. If they are left in that condition they are apt to injure themselves in trying to pull free and if left too long will die.


Feeding the Breeders. Breeding ducks are fed twice a day, in the morning and at night. It is usual practice to feed the breeders last in the morning and first at night. The reason for feeding them last in the morning is that they are usually fed in the yards rather than the house and they should be kept in until they are through laying which will be after daylight. A good breeding ration consists of the following, the proportions being given by measure in bushels.

  
1 bushel bran.
1 bushel low-grade flour.
1 bushel corn meal.
1 bushel green feed.
1/2 bushel either raw or cooked vegetables.
1 bushel in 10 of beef scrap.
1/2 bushel in 10 of cooked fish.

This ration will keep the breeding ducks in good flesh but there will be no difficulty in their getting too fat. It is also a good laying ration and will promote good egg production. The vegetables used in this ration usually consist of sugar beets, cow beets, potatoes, etc. However, if potatoes are used the amount of flour in the ration should be reduced a little so as not to make the ration too heavy. Beets, when used, are fed raw cut up and mixed in the feed. Small potatoes, boiled and mixed in the feed are more valuable as they have a greater food value than beets. Some duck growers feed fish entirely, using no beef scrap. This is done where a plentiful supply of fish can be secured by going out into the bay after them. However, this is not very good practice for a sufficient supply of fish may not always be available and the ducks are so fond of the fish that they will not eat well the beef scrap used as a substitute for the fish, until they have become used to it. Fish is prepared for feeding by boiling it thoroughly in a feed cooker.

The available land on the plant is used to grow a supply of green feed. Rye is used for this purpose early in the spring as soon as it is high enough to mow. It is mowed the first time when it is like a lawn. At this stage it does not have to be cut up. Oats are used in the same way. During the summer fodder corn is used. This is the poorest crop for the purpose but is as a rule the only one available at that time. Rape is sowed in August and its use begun about the time of the first frost and kept up until the hard freezes come or until it is buried under the snow. Creek grass which is secured from the fresh water streams on Long Island by going out in a flat bottom boat and raking it off the creek bottom with a wooden rake, is very much relished by the ducks and is used whenever it is available. However, the supply of this material is not as plentiful as it was formerly and it is rather hard to get. When it is available it can be used either in winter or summer.

Good field clover cut up and boiled with the potatoes or with the fish makes a good green feed. All of these green materials for use in the ration, unless they are already in short lengths, are cut up by means of a power feed cutter before they are mixed in the mash. When no other form of green feed is available ground alfalfa is used but only half as much of this material is mixed with the ration as is used of any of the other kinds of green feed. Wherever possible the various duck yards should be used to grow a crop of green stuff such as oats or rye as this not only helps out on the supply of green feed but also helps to sweeten the soil. The growing of a crop on the heavier types of soil used for ducks is especially important as such soils are more likely to become contaminated from the droppings.

The ration for the ducks is mixed up in a power feed mixer which works much on the principle of a power dough mixer. In fact, dough mixers are used on some plants. In mixing the feed enough water should be added to bring the material to a consistency where it will hold together when squeezed in the hand. In fact, the consistency should be between crumbly and sticky, but should never be sloppy. The feed is dumped from the mixer into a low horse drawn wagon and driven around to the various yards where it is shoveled off on to the feed troughs or trays. On some large duck plants a track is provided which runs over the yards and over this a car loaded with feed is pushed and the feed shoveled into the feed trays.

The breeders should be fed in the same place. If feeding is begun in the house this practice should be continued. If feeding is begun in the yards it should be continued there. To change disturbs the ducks and interferes with their egg production.

Coarse ground oyster shell about as large as corn should be kept before the breeders all the time in boxes where they can help themselves. A flock of 700 or 800 breeders will eat upwards of 200 pounds a week of this material. Unless sand is available in the yards where they can get it, ducks should also have access to a supply of good sharp creek sand but when kept in sand yards no other form of grit need be furnished.

The usual method of feeding is to utilize flat troughs on which the feed is shoveled. Only as much feed should be given at the regular feeding time as the ducks will eat up clean. This makes it necessary to watch the feeding carefully and to regulate the amount accordingly. It is good practice to gather up any feed that is left by the ducks so that it will not lie there to sour and spoil as such feed is bad for the birds.

 

Egg Production


The average egg production of Pekin ducks kept under commercial farm conditions will run from 80 to 125 eggs per head for the season. This will vary somewhat from year to year and also with the management and feed given the ducks. The laying begins to a small extent about December 1 and gradually increases until the ducks are laying freely in February. As the hot weather of summer begins to come on the laying drops off until about July 1 and after this not enough eggs are produced as a rule to pay to hold the breeding ducks longer. Often many ducks will stop laying considerably before this, especially those which have started laying early and it may not pay to keep such pens later than May. Laying takes place early in the morning and practically all the eggs are laid soon after daylight. It is for this reason that the ducks are usually shut up at night so that all the eggs laid will be secured as some of them would otherwise be lost by their being laid around in the yard or in the water. In the spring the ducks can be let out about 6 a. m., as the laying will be pretty well over by that time, but in winter they must be kept shut up later in order to secure all the eggs. After the ducks start laying in the spring they are very regular and continuous layers and will miss fewer days than most hens.

After the breeding ducks are first put in the breeding pens and shut in the houses at night it is common practice to use electric lights for the first 2 or 3 weeks in order to keep them from stampeding as ducks in strange surroundings are quite nervous and are quite likely to stampede and to run over one another thus causing cripples. Electric lights have also been used to some extent during the late fall and winter for the purpose of inducing egg production earlier than the natural season. As a rule the ducks can be started to laying about 4 weeks after turning on the lights but the average production under this system is not likely to run more than 60 eggs for the season as so handled they moult quite early in the spring. A single 25 watt light is sufficient for a house or pen 16 x 24 feet and the lights are left turned on all night.

The object in feeding and caring for the breeding ducks is to keep them from moulting and to keep them laying as long as possible. It must be remembered that any radical change in feed or manner of feeding, shutting them up too closely, change of temperature, or other disturbing conditions are likely to cause moulting and to check egg production. Any change in feed must be made carefully and gradually, not suddenly. It must also be remembered that ducks are excitable birds and must be handled and driven carefully so as to disturb them as little as possible.

 

Time of Marketing Breeders

The breeders should be turned off to market whenever their egg production drops off so decidedly that it no longer pays to hold them. In most cases this will be about the 1st of July but it may range considerably earlier than this, especially with pens of ducks that have started laying early. When the ducks finish laying their eggs they begin to moult and it is at this time that they should be marketed. If marketing is delayed, the ducks will lose condition as the moulting progresses and will therefore be held at a loss.

 

Diseases and Pests


Disease. Old ducks, that is, mature ducks, are practically free from disease. Of course, there will be a certain amount of loss in the breeding stock from various causes but this should not run for the entire season more than 10% of the flock. Ducks do not become egg bound, but sometimes, especially during heavy laying, they become ruptured.


Insect Pests. Ducks are remarkably free from lice and other insect pests and those which they do have do not trouble them much. It is unnecessary therefore to take any precautions in the way of treating the ducks to keep them free of insects.


Dogs. Occasionally trouble may be experienced from dogs. If these animals get into the yards with the breeders or the fattening ducks, they may kill a good many and in addition will seriously injure the rest by chasing them and by the fright which the ducks are given. _
