So I got my chicks last week and didn't really notice at the time, but one of the PR's has a "weird" comb. PICS below, obviously... I know that they are supposed to have a single comb and my other PR seems to be developing a normal looking comb. But this "weird" one is almost like a scab and is dark. Do you think it was damaged or hurt? Normal behaviour, etc. Any ideas? Oh, and please ignore the posture. I was getting the evil "take the darn camera AWAY" look.
