I went out to fill the feeder so I had the feed scoop in my hands and the keys to lock in the other...trying to unlock the coop. I was up on a step and felt this BAM from behind on my legs! I lost my footing and got bumped off the step. It was so strong that I gripped the lock in attempt to catch my fall and ripped the bottom of the lock off. I gave him a deep noise and a few stomps to let him know I am boss...and attempting to FEED them. Thought it was a one time thing and went out yesterday to a full blown battle with the guy. He was raised by mother hen but I did try to hold him when he was young and pat each one on the roost each night so they know I am friendly. The battle went on and on he kept bumping my legs but not pecking me. Every time he would bang his chest into me I would push him back with the side of my foot and yell in a deep voice. He didn't flinch. Just kept puffing up and slamming me. I was dropping the feed all over so figured I would take a handful and throw it to get him to back off. I threw it into the run, he ran in and I shut the dummy in. Now I don't want to let him out but feel bad for the poor hens who are sweet and want to free range around the yard. I guess I am wondering, will he get worse??? Or is he in his preteen bully stage and grow out of it. He is 6 months old.
