Alright, so my two silkies were out free-ranging and I noticed my white rooster Sugar (who just started crowing!) was limping. I picked him up and looked at his foot, and there appears to be a small injury on his middle toe. It looks like the top layer of his skin was scraped off somehow. The underneath layer that is now exposed is skin, not flesh, and it's not bleeding, just soft and tender. It almost looks like shedding snakeskin. I wouldn't be concerned, except that he does have a pronounced limp and therefore must be in a bit of pain. Any suggestions on medical treatment? Should I just let it heal on its own?
