We recently got 20 chicks. 4 Easter Eggers, 4 SLW, 4 GLW, 4 Buff Orpingtons and 4 RIR. We had Silkies a couple of years ago and I never had any problem with them pecking each other. It started last Sunday when we saw one of our easter eggers had a bloody tail. We removed her to let her heal. Then on Thursday we found 2 more with bloody tails, an Easter Egger and a RIR. We also saw 2 RIR doing the pecking. So we separated them all to their own space, let the bloody ones heal and the RIR's to stop pecking. Fast forward to this morning. We put back the RIR that was bloody and now I am watching her go around and peck each bird one by one. The others are interested in their food/scratch and she's eating the food as well but her main goal to walk around pecking everyone. I've read on here about the pinetar which I plan on picking up when out tomorrow. Is there anything else I can do to try and stop it (today) besides removing her again? Are my 3 RIR ever going to be able to live with the others? They just seem like such bullies ! Thanks for any help. I forgot to mention they are 5 1/2 weeks old.
