I’ve often read that perches for chickens should be two inches wide or more. Some people recommend four inches. It’s also recommended that the perches should be flat. When the chickens here go up a tree, they don’t choose to roost on the wide branches, they seem to prefer branches that they can curl their toes around; nothing like four inches wide and usually under two. When chickens walk, they don’t bend their toes much. When chickens scratch the ground they don’t bend their toes much either, The chickens front toes have two joints and the back, a single joint. What are these joints for if not to grip a perch? Most of the actions I see chickens do with their feet don’t require the degree of articulation that they have available. I’ve read that flat wide perches reduce the occurrences of bumble foot, but I thought bumble foot was caused by repeated high force impact sometimes received by jumping on perches placed too high, nothing to do with the perches width, or shape. I’ve also read that wide perches help keep the chickens foot warm, but I get chickens who have sat on eggs with aggravated scaly mite because the feet don’t receive adequate ventilation and stay damp and warm. So, why do people recommend wide perches? Is there any science behind these recommendations? I’ve posted this in this section because if the recommendations are wrong and there is no science behind them then given time we’ll end up with flat footed chickens.
