I have 3 x 6month olds, and 1 x 8month old Roosters and they tend to crow almost every 15mins to half hour every night. I love my Roo's and i actually enjoy hearing them crow, but if they crow all night doesnt that mean theyre not getting enough sleep? If they are awake all night crowing wont they run themselves down and wear themselves out?? And why do they feel the need to do it? My older 12month old roo doesnt do it with them. I wouldve thought they'd have got it under control by now, crow at dawn, and during the day, sleep at night unless disturbed, but doesnt seem to be happening... They arnt crowing as a warning, there havent been any predators around. There are no lights on during the night to disturb them, only the moonlight but even that doesnt get very bright. Should i block the light out of the coop completly, maybe hang some hessian or heavy cloth over the door and windows? I read that if you lock them up where they cant stretch their necks out they wont crow, but i dont want to do that to them. Are there any other suggestions or input you guys might have?
