crowing cockerels

Hello everyone. Does anyone out there have the same problem as me? My cockerels appear to be crowing throughout the night. I dont mind but I,m sure my neighbours do. I,ve tried shutting the pop hole but that didnt work. Could it be that because I have 2 cocks they are crowing for status? :

I had just one cockerel, Bob Dylan. He'd doodle do at all hours   
It probably isn't helping having the 2, one will no doubt set the other off.

If you can make sure their house is as dark as possible that might help. However, more than one cockerel does make them noisier Im afraid.

we have just got a white loghorn cock. So far he's brill. He crows twice just as the sun starts to rise, and that's it. He does sometimes crow during the day, too. The old boy we got him from said if cockerels are a problem, people used to "hood" them at night, a bit like a falcons hood. Not sure if I'd want to try it but if it saves a noisy bird from having to go, maybe.... has anyone else heard of this.
