I have 4 four day old Ameracauna chicks I got from the feed store. Two days ago, I noticed they were picking on each others eye lids, so I did some quick separation to try to stem it. The injured chicks are all doing very well. I've singled out the culprit. I put everyone together and within 1 minute, Bully had already attacked 2 chicks and was zeroing in on the 3rd. Bully is now living by herself indefinitely, unless I can figured out how to solve this. I have tried: Putting them outside in a huge 8x16 ft pen with lots of distractions, no luck. Bringing them inside and put them under a red light as suggested in my previous post here. Didn't deter Bully at all. So, have any of you ever had this issue, and how did you solve it?
