I'm new to chicken ownership and have been loving every minute, but have a concern about one of my one-month old RIR chicks who has developed a "curly" toe on both feet. I never noticed anything until maybe two weeks ago, but it doesn't seem to be getting any better. She doesn't have any problem walking, or perching so far it seems and she doesn't seem to mind when I try to straighten it. Should I worry or do something, or will she just have unique feet?
