Where the flock is small and the birds are to be allowed to select their own mates, all that is necessary is to watch them closely until all are mated or it is evident that there is a surplus of one sex. Surplus males will quarrel persistently with the other males and endeavor to coax their mates away from them. The unmated males must be provided with mates or removed from the loft. Unmated females are not so readily noticed except when there are only a few birds in the loft, but by close watching they will soon be found. When a start is to be made with quite a large number of unmated birds, the best plan is to put the flock first in a different apartment from that in which they are to be kept permanently, and, as each pair mate and begin to build their nest, remove them to their permanent quarters.

When it is desired to mate a particular male and female, the best way is to place them one in each side of a small coop with a wire partition across the middle. This coop should be put where they cannot see other pigeons. Sometimes one of the birds shows a decided antipathy to the other. In such a case it is, as a rule, useless to continue efforts to induce them to pair. In most cases, however, the birds will soon show mutual affection. When this stage is reached, they may be taken to the loft and released. Short coarse straw or fine twigs should be placed where pigeons that are building nests can take what they want. No nest box or pan is really needed, but many pigeon keepers use a nest bowl, called a nappy, of earthenware or wood fiber.
Feeding. The food of pigeons consists almost wholly of grains and seeds. The principal grains used in America are wheat and corn (usually cracked corn). Field peas are also used quite extensively. While pigeons will eat the same kinds of ground-grain products as are fed to poultry, pigeon keepers rarely use such foods. They prefer to give a variety of hard grains and seeds. Those who keep large stocks of pigeons often buy separately the feeds which they use, and mix the grains to suit themselves, or feed them in such alternation as seems desirable. People who keep only a few pairs of pigeons usually find it more satisfactory to buy the feed mixtures sold by dealers in pigeons' supplies. As a rule, old grain and seed that are very dry and hard are best for pigeons, and especially for exhibition and breeding stock.
