Ok I have been a very very bad chicken mom. I incubated and raised chicks this year and ended up with masses of roosters. Seriously masses. We were around 20 ( a couple are questionable still). We had to kill 7 today. They ran almost like a pack and attacked everything. Terrorized my poor hens. We spend a ton of time trying to keep them away from them. Stupid I know, it needed to be taken care of but time could never be found with my husband. New job position and parents to do list. So today he ended up having to do a quick killing job after they killed my daughters bantam roo and tore up a hen. They were on a roll and I could not even get them into a different area. I thought I had time. i have had this many before and never, ever did they act like this. This was a group raised together and they were just terrible. Thinking maybe I should not have separated them from all my suspected female chicks when they were little. First year I did this and I wonder if it made them more agressive. All mine free range and I do not have enough facilities to keep that many males separate from the females and each other. Never saw anything like this. Other than culling males early, how do you that raise your own deal with this? I think next year we set a date and just get it over with. He can schedule vacation time or something. It went from everyone was fine to 2 weeks later having this issue.
