I have a black Ameraucana hen? that is of this way also. Over a year old and never layed an egg, although I had in the past found her in the nest. Hen feathering and always hung with the girls. Her comb however is large for a hen and bright red. Just over a month ago she started crowing, really crowing. It only went on for about a week. She hasn\'t crowed since, but I\'m thinking its because my new batch of young cockeral are grown up now and crowing themselves. She is still displaying male behaviour like dropping her wing and dancing around the other males. Haven\'t seen her do anything like that with the females though.
