Pigeons require, besides the grain they eat, salt, grit, and charcoal. These should be kept in the lofts constantly, so that the birds can get at them at any time.
GRIT
Pigeons must have grit and plenty of it at all times. Moreover this grit should contain some tonic mixture and other essentials to keep the birds in the best of working order. Many breeders fail to supply their birds with grit of the right sort and for that reason do not get the best results from their birds.
There are many so-called "Health Grits" on the market and many of them with more or less merit but grits are heavy and freight and express charges are high so it is usually best for the breeder to secure clean sharp sand and mix the grit at home. There is great saving in this and at the same time better results are obtained.
SALT
Salt is absolutely necessary to the health of the pigeons. It should never be given them in the form of table salt, because they will eat too much of it. If rock salt can be secured, it is the best form in which to give salt to the pigeons. If this is not procurable, buy a five-pound bag of table salt and wet it. Then put it in the oven and dry it, when it will become almost as hard as the original rock salt. Put a bag in each loft and let the pigeons pick out the salt through the bag.
CHARCOAL
Charcoal keeps the birds in good condition and a cigar box full of charcoal, broken into bits about the size of wheat grains, should constantly be kept before the birds. This crushed charcoal is to be found in poultry supply stores. If none of these are within reach, the pigeon-breeder may make his own charcoal by burning wood to a coal and then extinguishing the fire with water. Corn cobs, charred in this way, make an excellent charcoal for pigeons.
