Mine stopped crowing for over a week after one of the girls was killed by a raccoon in the middle of the afternoon. We figured he was either traumatized, or the girls told him to shut up and quite drawing so much attention to everyone.... Since starting back up, he crows about every half hour almost all day long, so my guess is he was traumatized and now he is trying to convince all creatures great and small that he is the king of the world.
