I've got a big beautiful Bourbon Red hen, maybe 2 years old, and she's always lived in a mixed flock of chickens, ducks, and other turkeys with no incident. She's either kept to herself or happily mingled with the rest, until this past week. Suddenly, she's beating the living daylights out of our ducks, and almost killed the drake. I had to wrestle her into a large dog kennel to keep her from finishing the job, and she's still there now. Nothing in her environment has changed, there have been no new flock members added. She DID go broody a few weeks ago and sat for about three weeks before abandoning her nest, so I'm wondering if this is some sort of hormonal issue making her ****** off and aggressive? I'd rather not eat her, but if there's no hope of rehabilitating her, she'll be dinner.
