Walt,
If one is doing JUST poultry, I would agree with you. There's no way to recoup the expense. However, I think it could be done profitably as part of an integrated operation. Other than dairy farmers, I don't know anyone around here that keeps just one thing. Even the shepherds hereabouts keep a few pigs and beef cattle to round out the farm. I would think that chickens could be a profitable part of a total agricultural operation. But if one is in backyard poultry for poultry's sake, expect to loos money every year.
