I've rarely seen any bullying in my flock. I have 20 total right now and they have a very large run they go out in every day. I noticed that Happy, one of my black australorps has been staying in the coop most of the day. I've realized it's because when she goes outside, she is being ganged up on and attacked by a small group of the others. The strange part is that it's Happy's old group. I still have the 4 barred rocks and 2 australorps from my original flock. They turned 5 this spring and have always liked to hang out together. Now, for some reason they've all turned on Happy. I took her out to the food the other day and stood there to keep an eye out and she ate because she's hungry. but when she headed back to the coop they ambushed her and started pecking at her. Any ideas about how I can reintegrate her and stop this behavior? I've been feeding her inside the coop when the others are busy with their morning mash, but she can't just spend the rest of her life on a perch indoors. What can I do?
