. Principles and practice of poultry culture . Poultry. Fig. 305. Six-weeks ducklings at Weber Brothers' duck farm. Fruit trees just set out in yards number of young birds in a single natural brood rarely exceeds ten, the number in a group of such broods is rarely greater than twenty- five or thirty. The mothers, with their young, forage either in- dependently or in groups of two or three broods. The different broods usually separate at night, if accommodations permit. If several mothers with large broods sit close together, it will usually be found that some of the young soon show the effects of crowd- ing, especially when they are in a small coop or in a corner, and when the circulation of the air is slow, — for the movement of the air is slightly, if at all, influ- enced by the number of birds at the spot, while the condition of the air depends on the number of birds breathing it. This is equally true as to the air in a brooder. If the mothers are kept separate, or have an opportunity to follow the natural inclination to keep the broods separate at night, there is no trouble from crowding at that time. After the young birds are weaned, they will, if left to them- selves, keep well distributed. It is a common practice at that time, how- ever, to combine broods into larger groups before putting them into new quarters; from putting too many birds into small, ill-ventilated coops, and from the tendency of the birds to huddle together when they are moved to new quarters and the natural groups are broken up, this stage of the life of young chickens is especially full of troubles due to overcrowding, aggra- vated, in many cases, because it comes just at the season when weather conditions make crowding most disastrous. In the artificial rearing of poultry larger numbers of young birds are placed together from the first. The primary object is to. Fig. 306. Chickens in double piano- box house in orchard.
