We have a flock of 70. One stands out and I have named her "Millicent The Magnificent". She is a deeper richer brown than all the others, she has a much larger comb of a deeper red than all the others, and she even has racing stripes! But we're starting to wonder if "she" is a "he". Millie is always alone, often the only one in the coop when everyone else is outside, and we seldom see her eat even when we toss scratch at her feet. She doesn't take any proprietry interest or care in the others, and doesn't crow. She's 9 months old. She has an almost haughty air. Is it possible she's a cock?
