We have 6 chickens around 10 weeks old. This particular one starting crowing a few days ago. I didn't believe it until I ears it for myself this morning. It's a sad cockadoodledoo so I'm not fully convinced she could be a rooster. She is the most dominant of the bunch, and getting to be the biggest. But the 3 Isa Browns stand up to her/him. Is this normal? Am I neglecting him/her? What can I do? I have a video of the crowing if I can figure out how to upload.
