I have a golden comet rooster named Oliver and he is one of the most docile birds I've ever met. I believe it's because he was the yellowest, fluffiest, cutest chick and therefore he was handled the most. He is nearly one year old. We got him in batch of a dozen chicks last year, and being naive we didn't have them sexed. We ended up with 5 roosters and 7 hens of different breeds. We have narrowed down our number of roosters to Oliver, one other Golden Comet rooster named Lyle, and two male bantams. Recently we killed two highly aggressive RIR roosters we had, and since then Oliver has become a little bit more aggressive. He now does the mating dance in a circle around me whenever I'm outside, and recently he used his spurs on my 5 year old sister! He used to be so docile I could hold him and stroke his waddles. These days he is a little bit mean. When I get ahold of him he immediately calms down and doesn't peck, but the fact that he attacked my little sis really disturbs me. Right now,due to some marten attacks over the winter,our male to female ratio is even. Is this why Oliver has been acting up? We have an order of ten female chicks arriving in April. Will Oliver calm down once we have more females? Or should I get rid of him? Oliver is my baby, and I really would like to keep him if there's any way to keep him from attacking a human again.
