This practical man says further: "It is our experience that the majority of the people going into the poultry business go in 'blind.' Their chicken houses are put up irrespective of range facilities and then after two or three years when they begin to run into trouble they find their mistakes. I would suggest that you point out to prospective poultrymen the advisability of first, buying land and developing their own poultry plant rather than trying to make over someone else's plant; second, buying in a location where buying and selling facilities have been developed; third, getting in touch with a reliable local poultryman for guidance in laying out his plant and following only one advisor. By hooking up with only one poultryman he is presented with one way of doing things which this poultryman has found successful in his own business." Another successful man states that the most economical time to start the business is in the spring when day-old chicks can be secured and purchased at a lower cost than is possible in the buying of laying stock at other seasons of the year. He further advises that the greatest mistake made by many starting in the poultry business is the lack of adequate capital. Too many invest all of their money before any income can be secured, according to this man. Should there be a set-back during the first year or two, there is no way of continuing and the whole investment may be lost. Still another practical man states that "Site is, in my opinion, the most important factor to be considered after the decision is made that a person wishes to go into the poultry business. Successful poultry keeping probably requires more careful selection of a farm than any other agricultural industry. There should be light soil with good air and water drainage and an area of sufficient size to permit shifting the poultry on different areas as a means of preventing disease infection and as a means of securing vigor in the birds." He, too, points out that old poultry farms should not be considered by prospective poultrymen unless they have been approved by an expert in these lines, for the reason that these farms are frequently offered for sale because of persistent disease infection which it is very difficult to eliminate, or because of some fundamental difficulty, such as poor soil drainage.
