One of my hens has gone broody, and since I'm not getting fertile eggs I've been trying to break her. Due to my work schedule my attempts are "[email protected]$$ed" so to speak. When I get home in the evenings, usually around 6:00, I take her off the nest, toss her out the door and shut the coop door until its time for them to roost. As soon as she exits the coop, my not-quite-1-yr-old rooster puffs up and runs at her like she is an intruder and attacks her. If she runs, he chases her. This went on for about 15 mins last night and the night before. Even after he calms down he will still randomly go after her. She walks around all puffed up like a turkey tom, growling and making odd sounds, I'm sure because she's mad she can't get back in the coop. Is it that behavior that is setting off my rooster? Surely he knows who she is even though she's been in the coop all day; they can't have that short of a memory. This morning since I had the day off I booted her out first thing, and he still attacked her. He had not had an issue with her before she went broody. This is my first time with a rooster. Can anyone explain this behavior?
