HI everyone, I noticed some of my girls have small black spots on there combs today . I didn't notice them yesterday. could they be getting frost bite it is in the teens here and I'm sure even less with the wind chill. I'm not having a good chicken week .I've done some research and came up with fowl pox or frostbite .If it is pox what do you do and are any eggs layed ok to eat. They just started to lay about 10 days ago.
