Saturday a dog broke into my large wooded run and grabbed one of my hens. I chased him and he dropped her and she lost a fair few feathers on her back toward her tail but seemed to bounce back. She has laid eggs each day since then (she is the only one laying right now) and seemed to be perky and OK. Today is Tuesday and I found her this morning standing in her nest box looking dismal - all puffed up, eyes barely open. I am very concerned. Do you think she might have internal bleeding? Infection? Help please! If she doesn't look better in a couple of hours I will bring her inside (I can rig up a chicken hospital in the guest bath) but don't know what to do. All advice appreciated. Thank you!
