We bought a mixed flock of 5 chicks from Meyer Hatchery on June 1. All of them were supposed to be females. This very friendly Australorp has had a red comb since almost 5 weeks. She's top of the pecking order, for sure. We were trying to convince ourselves that she was just early to mature because she was in charge. Then the tail feathers started to curve, and we've started hearing some odd crow-like sounds coming from the coop in the early mornings. She's a rooster, isn't she?
