I have an Ameraucana rooster who is 17 weeks old, and began crowing over a month ago. He had a really strong crow and crowed all the time. He is a noisy boy, always talking. A few weeks ago his crow sounded weak, and now he doesn't crow at all. He free ranges all day, but he is eating the same food and getting all the same treats. He seems fine, he still likes to talk just as much as he did. Does anyone have any explanation as to why he stopped crowing all of a sudden?
