Excerpt from Efficient Poultry Housing
Heretofore, the long, narrow house with a hallway in the rear and long, narrow yards running off from each pen, Where separate matings are necessary, has been the standard type of intensive poultry culture on a large scale. Standing at o... ne end of this hallway, one sees the lines of the walls gradually converge to a little speck at the farther end as if one were looking at infinity down the Corridors of Time, and one could not help but have pity for the attendant who reached the remote end only to find he had forgotten something at the starting point. Nor could one look at the breeding pens in long narrow yards with freedom to move in only one direction, with out a feeling of how different this artificial environment was from that of the Gallus bankiva in the jungles of India and the Asiatic Islands. And this feeling was sure to result in a better understanding of infertility in hatching eggs and lack of vitality in the few chicks hatched from eggs from such matings. But the unsuitability of such houses for breeding stock was soon recognized and so-called colony houses were erected, scattered over many acres and involving so much labor in caring for the birds that frequently financial disaster resulted. Recognizing how large and impor tant a factor labor is in poultry curture, breeders found that large ¿ocks were prae tical and that they did away with much unnecessary labor. Elated at their success with large ¿ocks, one farm boasted of the fact that with units of 500 layers, one man could attend to the fowls in four houses without assistance, but qualified it by saying that he was an unusual man. Another farm, which was the first to demonstrate the practicability of putting layers in one ¿ock, had three men constantly em ployed to care for layers and the necessary chicks, incubators, breeders, etc, to produce them. About the only progress that has been made in labor saving methods, excluding appliances, has been in increasing the size of ¿ocks. The old, long house or scattered colony houses are still sine qua non of the poultry farm. In either case the labor of caring for poultry is from three to ten times What it should be.
