I've searched this site as well as the web and the only thing I have seen about what the red blotches are on my hens feet is frost bite, however it has been 70-90*. So I'm not thinking that is the issue. She hasn't laid an egg in over a month and I thought it might just be her age but I've noticed the red spots as well as her combs not looking as viberant as they have been in the past. Could it just be signs of old age? Not sure how old she is. We have had her for a little over two years and recieved her from a friend who could no longer have chickens and they said they had her for about three years. I've read that chickens will lay up to the end of their life (living 10-12 years) so I'm at a loss. Is this an illness that is causing this issue? Any advice is helpful.
