Hen or Rooster?
Well, welcome to byc!
Are you asking about a specific 1? I have a hard time even seeing combs in most pictures to even tell what kind they are. And some other people seem to be really good at it. Hope you can get a response from some of them.
I love the guessing game! Good luck.
All of the lighter brown/white ones are pullets and they seem to be some kind of Red Sex Link. Do you know what breed of chickens they are? That would help.
