We had a Silkie get attacked by a dog. When I found her I thought she was dead for sure. I picked her up and she barely moved. I immediately cleaned her up and put blue lotion on her injuries. He neck is open in the back and showing the muscle the whole length of it. Her butt has a gaping gash and all of her feathers from midway to her butt were pulled off, including chunk of her tail with skin still attached. I put her in a box under our microwave light and got her warmed up. She now is on a dog crate in the kitchen. There is no sign of infection and wounds are healing up. All that being said, she really doesn't move around much still. She won't eat or drink on her own so I started tube feeding after 2 days. It's now one week and she really won't eat or drink still. She's a little more active (might take a step or two when I take her outside for some sunlight time, but for the most part she stands there motionless) . She has pooped. It started black and Is getting pretty normal. My question is anyine with experience of a hen shutting down, and how long for the healing process, not just for the visible skin, but internal issues that may have happened. How long should I keep up the tube feedings? What Should I expect as far as recovery time/milestones?
