I have a cockerel and 3 (suspected) hens that i raised that are now 13 weeks old. This cockerel has been top of the pecking order from day 1 and he only seems to have become worse as he gets older. He started trying to crow at 5 weeks old and he constantly picks a fight with the other hens or anything else he can find. Yesterday one of my poor hens had a chunk out the back of her head and was bleeding. Now im worried that its gone to far and this cockerel cannot be sold with such aggressive behaviour since i dont plan on keeping him myself. Is there any chance he will become less aggressive as he grows older?
