My rooster has been acting up lately. Today when I was feeding bringing water to my chicks in the brooder he ran into the back of my legs. I incubated these chicks and have them in a brooder in a separate shed from the chicken coop. So I don't think it was him protecting the chicks(he never even met them). Anyway he never ran into me before but he has ran at me and he even took a chunk out of my mothers leg from pecking her a while back and she loves him and treats him really well. I did hold him down after he ran into me but he keept pecking me( he has never done that before. I now have him locked in the coop so he cant hurt anyone. I let my chickens free range. What can I do to sort out this problem. He seems to run at me every time im feeding him and the hens, sometimes he pecks me when I put the feeder dont. Any ideas why he is doing this?
