I have 3 pullets free ranging in my backyard with a large coop and plenty of food, treats, and love for all. My light brahma has started harassing my brown leghorn. Not constantly but occasionally she will get pretty relentless. They are all laying under the mandarin tree together right now but earlier I looked out the window and saw Pepper (LB) chasing down Biache' (BL) and wouldn't stop until Biache' would lower her head in submission. I only saw her peck at her once and it wasn't very hard. She usually just herds her around with her chest. Biache' is two weeks or so younger than the other 2 and noticeably smaller. Red (RIR) doesn't seem effected by any of this. Pepper and Red still do the chicken dance (what I call it when they run/flap/jump at each other and get chesty as they meet) and neither seems to be the boss. Pepper has also started chasing bluejays out of the yard and I would swear she was about to charge the cat yesterday. She is coming in from the disabled list- she had a pretty sore leg that kept her from running and scratching for about 3 weeks but is getting close to 100% now. Is this just the pecking order process?
