I have 4 Buff Orpingtons that are 12 weeks old. All were sexed at the hatchery and SUPPOSED to be pullets. Dorothy has always been bigger than the other 3 (Blanche, Rose, and Sophia) and my husband jokes that’s she’s actually a rooster. She’s starting to crow but I’ve heard of hens crowing before so I’m holding out hope. What do y’all think?
