Excerpt from The Chick Book: From the Breeding Pen Through the Shell to Maturity
That the up-to-date hatchers can be depended upon to do their full share toward making the poultryman inde pendent requires no argument. Good eggs and proper hand ling by the operator will assure good hatches of vigorous chicks. An understanding of the machine and how to con trol it, with some knowledge of how to treat eggs during the period of incubation and of the essentials of correct environments, constitutes the wisdom required for successful hatching.
We find incubators operating in dark cellars, where there is no light except that of burning kerosene; where good air enters by chance and not from intention, and the atmosphere is damp and laden with germs of decay and dis ease. Again we hnd them located in rooms above ground, in houses built for the purpose in dwellings and in rooms partitioned off in the barn, poultry house and shed where the air, though dry, is seldom renewed and light from the sun is rigidly excluded that a more even temperature may be maintained.
