This is a 4 -5 week Chick, she (I hope) went to a friends house, seperated from the 25 chicks, and they decided to switch to another turkin. I brought her home, and didn't notice until yesterday, she was hiding (3 days later) , the others were picking on her apparently. When I got a closer look I saw she was reddened. I put her in her own area, and she is acting like a healthy chicken, without the bullies. Scratching for grain, eating, being a normal chick. But, is this something serious? She still was red this morning. Any advice how long to keep her alone? Any help appreciated.
