I don't know what this is, so maybe someone out there can tell me. One of my chickens, a Leghorn mix, has white scales or something on one leg. She is not limping, eats, poops, drinks water and generally is acting just fine. I have all hens and they are fenced inside a large enclosure with trees, bushes, etc. So they "free range" within a yard. She is one of nine and seems to get along just fine, however she can be a bully at times. I feed them laying pellets enchanced with lots of treats. They have a bowl of oyster shell and plenty of bugs available. Hope it's not serious. Thanks.
