Economy of labor (when snow does not lie long on the ground) and larger utilization of unskilled labor. Birds kept under natural conditions do not require the constant dieting and nursing. Fig. 92. Pittsfield Poultry Farm, Pittsfield, Maine, where intensive and extensive systems are combined, large yards for adult stock and young stock grown in orchards on the colony system too often necessary on intensive plants, and many things to which the intensive poultry keeper must give his constant personal attention may safely be left to unskilled help. There is also less need of scrupulous cleanliness. 4. Economy of food ; the birds pick a large part of their living. 5. Improvement of land, and sometimes double cropping of land, especially with young poultry. 6. Stability of value of equipment; when small, movable houses are used, they are salable at their full value at any time. The disadvantages of the extensive or colony system are: 1. Added labor in bad weather, particularly when snow keeps the birds in the houses. 2. Unfavorable conditions for the birds when long confined to houses designed only for roosting and laying Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Robinson, John H.
