. Principles and practice of poultry culture . Poultry. 252 POULTRY CULTURE is necessary is to remove the empty shells, in order to give more room in the nest and to prevent an unhatched egg from being " capped " by a shell. Helping birds out of the sheU. On the principle that the bird that has not strength to get out of the shell unassisted is not worth keeping, most experienced poultrymen consider it inadvisable to help them out. Few, however, rigidly follow this rule. Espe- cially in hatching by natural methods, where the eggs are easy to get at, the attendant is likely to help out of the shell every chick that seems to need help, and discard the weak- lings later, when re- moving the chicks from the nests. This saves the chick that is held in the shell by some- thing else than lack of strength to make its way out under normal conditions. Such cases occur when the mem- branes dry as the chick picks around the shell, and when the chick is " mispresented " and picks at the small in- stead of the large end of the egg. If the drying of membranes as eggs are picked is general, it is a good plan to moisten the nest with tepid water, and also, if conditions are very bad, to sprinkle the floor of the apartment liberally. Except in such circumstances, it is not necessary to moisten eggs in process of incubation by the natural method. In removing the shell from a chick which seems to need help, the condition of the blood vessels in the membrane should be noted. While the blood still circulates in them, nothing should be done. The chick will be injured or killed by the bleeding that would follow the removal of shell and membrane. Conditions of good hatching. Success in hatching by natural methods depends on constant and careful attention to every detail. Fig. 280. Hen with brood of newly hatched chicks.
