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.
