One of our 'teenage' pullets survived a dog attack a couple of days ago. She was very spooked and I am surprised she survived given how scared she looked. But now it appears the only issue is with one of her legs. We can't even tell which one. She has been in a laundry basket and has been eating and drinking well, not moving around much although she can turn herself around. I can't see any sign of injury, and when we feel her feet/legs, there isn't anything unusual and she doesn't seem at all uncomfortable when we are doing it. But she definitely can;t hold herself up on her own. What's the prognosis? Will she heal if we keep her quiet long enough?
