Ok, got it. I thought you had said that Hector was injuring the ladies. Well, you could try putting Jill in chicken jail, in a dog crate inside their coop, for a few days, to see if that might help with the bullying, and change the dynamics some. I had to do that with a hen once. It took 2 attempts, 3 days the first time, and 4 days the second time, but after the second jail sentence, she caught on. I was prepared to go longer, had she not learned her lesson, but she did learn, and while she was the alpha hen, she was never truly mean ever again. I know it doesn't always work, but it might be worth a try.
