When the conditions are such that it may reasonably be supposed that the fowls can get all the food they require without going farther than fowls usually wander, the best way to determine whether this supposition is correct is to give them no food until evening, then throw out a little grain and see how much they will eat. If it appears that they need to be fed a considerable quantity, it is better to give a light feed in the morning and another in the evening than to give a heavy feed once a day, because if they learn to expect a full feed at a regular time, they will not forage so well. Fowls that have an opportunity to secure considerable food by foraging should never be fed so much in the morning that they will sit around for hours. When hens on a farm need only one or two light feeds a day, whatever grain is most convenient may be given them. Where they get so much exercise and a good variety of other foods, whole corn is as good as anything. A good way to feed it is to break the ears into short pieces and let the birds pick the grain from the cob. In winter the feeding of the farm flock should have more attention, especially if little food can be secured around the stables and stockyards. It is a good plan to give, once a day, a warm mash made of 1 part (by measure) of corn meal and 2 parts of bran, and to give as much grain at one other feeding as the hens will eat. Some farmers use sheaf oats for litter in the floors of their poultry houses, throwing in a sheaf or two as often as is necessary to keep a good depth of litter on the floor, and then give as much corn in addition as the hens will eat readily.

Any of the small grains and cracked corn may be fed in this way; whole corn needs longer soaking. In hard, freezing weather no more mash or soaked grain should be given than the fowls will eat before it can freeze. A favorite old-time practice still used on many farms is to heat shelled corn in the oven and feed it while warm.
