I'm new to Wheaten/Blue Wheaten Ameraucana breeding but I just hatched out 3 chicks. I'm trying to figure out if they're Wheaten or Blue Wheaten and pullets or cockerels. They are only 4 weeks old but I understand this breed is fairly straight forward to see at that age. Here are the 3: It may be hard to see but the last pic has black feathers at the very bottom of the wings. Thank you for any and all advice!
