Poultry--perhaps because of the fact that evolution resulted in the transformation of their forelimbs into wings, with a resultant greater strain on their remaining two legs-seem much like people in being bothered by "bad feet." Frequently the cause lies in a sort of "no man's land" between nutrition and management, but the fact remains that a host of disorders of the feet and legs of chickens and turkeys continues to plague the veterinarian, the nutritionist and the poultryman.
