I had one chick that would not stop pecking the others eyes, so I put it in "chicki prison" or maybe" time out" is a better term. Anyway, I left it in the same brooder, but put a wired cage/basket thing over it. I only put her in it for like 5 or 10 minutes at a time, but I did it a few times, and within the same day, she got the message and never pecked again. She could see everyone else, and they could see her, but she couldn't get to them. Something about removing her yet keeping her within the same enclosure workd for me. Hope it helps. They seem to stop all the wierd pecking by about 2 weeks of age, then they go on to bigger things, like chest bumping, stare downs, and leap frog. They are just looking for things to do, eat, etc. It won't be long and you can put real meal worms in there and then the fun really begins. Good luck!
