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.
