I have a not quite 3 month old roo who started crowing but has stopped. His comb had been red but has now gotten pale. He was in with 2 other roos that hatched the same time he did but he was getting a little aggressive with them so I put him in a separate dog crate where he could see them but not reach them. Since then he seems grumpy and sad. I've since moved him out to the garden shed where he is in a larger kennel and can see the adult hens who come over and socialize with him. Any thoughts? He is eating, drinking and pooping normally. Thanks!
