I've had my entire flock since day one, they all grew up together. Everything was completely normal yesterday. They were free ranging and all together as a group. Today when they were free ranging, I noticed one of my gold stars, Daisy, was completely separate from the rest. When it was time for them to go back in the run, I was near Daisy so I picked her up and brought her with while I herded the others in. (I frequently do this) As I put her down to go in, she turned and ran away from the run (very unusual for her). When I finally got her in, the others attacked her, pecking at her face. She "screamed" and ran into the coop. When I went to get her, she was on top of the feeder. I tried separating her in our other run, but that made all of the other chickens charge at the side of the fence because Daisy's run had grass in it. Daisy buried her head in a corner of the run and sat there. So, right now she is in a dog kennel in the house. She is eating, drinking, and pooping normally, although she seemed quite hungry. Any suggestions on what to do? Also, she is one of a few of them who are starting to molt. Thanks!
