This morning when i got up I went to my barn to check on my rooster because they kept fighting the day before but when i got out there i noticed that one rooster was looking at me weird. So looked at his eyes and noticed that his eye was closed. So when i got home from school i checked on them and noticed it was still shut. Could he maybe have gotten his eye pecked from fighting or is it something else? Also is the black stuff on the comb frostbite?
