I think I already know the answer to this but am in denial because I was sure this was a pullet up to this point. This is a barnyard mix chicken. She hatched around mid-February, putting her at around 11 weeks. She was the one I was sure was a hen, smaller, docile, nothing gave her away until very recently when I noticed some odd feathers appearing and her legs started looking thicker. - Any chance at all she is a she?
