I am brand new to chickens so I am not even sure if this is a problem but it sure doesn't LOOK normal to me. I have three chickens. Two Buff Orpingtons and an Easter Egger. There are these black marks on both of my BOs that I just noticed. The EE does not have them. Here are some pics: This one has it on her face and wattle. And this one just has it on the tip of her comb. I live in Texas and it hasn't gone below freezing so it can't be frostbite and I've never seen them peck at each other or be aggressive so I don't THINK it is a pecking injury but obviously I don't see them all the time. Any help would be appreciated.
