I have a flock of seven hens, just over two years old. They've never had a rooster. Since the time they were only a few weeks old my Black Australorp has been the "top hen", she is small compared to some of my other breeds but she is feisty. She has never been a good layer-maybe a few eggs a week & a few months ago she stopped laying & squatting all together. She doesn't crow like a rooster but she does sound alarms to alert the flock of danger & she "sings" everytime someone else lays an egg, she often goes in the coop to watch them lay. She is absolutely at the top of the pecking order & its my theory that she has become too masculine to lay. Is this possible? Has anyone ever seen this happen or is she just not a good layer?
