New to chickens and we purchased 4 unsexed baby chicks. One of the icelandics was developing differently then the other and started crowing - we dispatched him but now a few weeks later the hen looking one DEFINITELY looks like a (beautiful) rooster to me. The blue copper Marans we were sure we're pullets up until a week ago but now things are much redder and they've both started being noisy early in the morning. This started a few days after dispatching the OG rooster. Can anyone confirm that these are all cockerels? Any hope the coppers are just noisy pullets?
