Bumble foot is a pussy core in the pad of the foot which swells and causes the bird to go lame. If you can remove the core and clear up the infection you can sometimes correct his problem. Bumble foot can also be a problem for birds raised on gravel, concrete floors, or hard- packed ground. Improper diet - Starter diets that are adequate for laying chickens do not do the job in meat chickens, turkeys, and waterfowl. Use a complete starter and grower mash balanced for the specific types of fowl whenever possible.
People often feed whole grains to young fowl trying to save money.
This often results in nutritional deficiencies that causes lameness. Improper equipment - Make sure any mesh wire brooders are small enough to prevent the young fowl from getting their hocks stuck in the wire. Be sure doorways are large enough for the birds to move through easily. Make sure ramps have good traction for the bird. Use ramps and walkways so the birds do not crowd over a high sill or jump onto hard ground from elevated doorways.
