I have only had a couple roosters my whole time having chickens. This rooster is fabulous, absolutely love him, but he crows in the middle of the night. He will begin around 2AM, it is not light, there is no sun, only moonlight and he will crow until, well I guess he never really stops. During the day its very infrequent, doesn't crow at all after noon or evening but at 2AM every night, its every 60 seconds. Whats up?
