Hi everyone, This is our first time keeping chickens and we could use some help. We have ten birds who we got as 2 week old chicks, they are 14 weeks old now. A few days ago I noticed one of the hens was being attacked repeatedly and it sounded vicious. On one occasion I saw two or three of them pulling on her from different directions, it was awful. Yesterday morning she got chased around and managed to escape the electric netting, so I put her back in but started to worry. I have read that chickens will attack and kill a sick or hurt flock member. I noticed yesterday that she looks lethargic. She just stands there with her head hunched back into her feathers and doesn't do anything. The others are always busy pecking, chatting, scratching. The most she'll do is a very soft, cute little "tut tut" noise. I can pet her, pick her up, and hold her for a long time and she doesn't care, which isn't normal for our birds since they weren't handled enough as chicks. Last night she didn't come back to the coop with everyone else at bedtime, and we hunted around for quite some time before we found her hiding near the stream. We tried putting her in the old brooder box to give her a break and isolate her in case she has something contagious, but she got upset and smacked her head on the wire a few times trying to get out, so we put her back in the coop and hoped for the best. Today I saw another hen pull some feathers off of her and she didn't react. She didn't want to go outside with everyone else, just stayed in the coop. I put the rest of the flock out on the grass and blocked them from going back into the coop/run, so she could get a break from harassment and try to recover. She will drink water but seems to struggle with eating, so I put some water in a bowl with food pellets and a bit of vegetable oil in case maybe she is blocked up or something, she had a bit of that but definitely prefers just water. When I checked a few hours later she was still standing in the same spot, maybe moved two steps, still hunched. I did see her peck at the food bowl a tiny bit. As for physical symptoms, I don't see anything obvious. She has a very small wound on the top of her beak but doesn't look problematic, I can't see any other signs of injury. Her eyes are clear, she doesn't seem pale, she's not wheezing or anything. I'm not sure where to go from here. Should we keep her isolated or will that stress her more? Is there something I can do or look at to figure out what's wrong with her?
