All of these are within the last week. There aren’t any good body ones over the last week. I plan to take full pics on Monday, they’ll be 10 weeks old then. This one had a bright red crest at 6 weeks. They looked identical at arrival! Buff Orpington are Supposed to be autosexing, so I keep hoping I’m wrong, but he’s just so different than the other one!Hi and welcome to BYC!
Can you post a full body picture of the one you're worried about? Maybe it's just a fast developing pullet?
