This chicken is about 12 weeks old and was sold to me as a chick sexed as a female. She has outgrown the rest of my flock, despite supposedly being the same age, and is the head of the hierarchy. I e also noticed that she has started dropping one wing and circling one of my hens that is older and laying. I’m wondering if she is actually a cockerel? Please let me know what y’all think. She has not crowed that I am aware of.
