I know I have not been on here in a while. Huge family issues have precluded me being here really. But, last night a barred rock accidentally got locked out of the coop, but in the run. This morning when I found her she was plucked. Her belly and vent area are bare. She has big patches missing from her wings. She looks like she was picked on by the other hens, but I am sure she hasn't looked this bad before. There is an area under the run fence that is dug out. It is pretty small. She seems OK otherwise. She is clear eyed and energetic. I brought her in the house and put her in a cage. She has eaten corn, tomato and apple. (She's probably thinking she died and went to heaven!) It is cold here now and I am afraid she won't do well in the cold so bare. How long will I nee to keep her in to re-grow her feathers? What could or would do something like this?? Sorry to vanish for moths and then come back seeking help, but I hope you will help her anyway.
