About one week ago, we lost 3 of our 10 week old chicks to something that got into our chicken coop at night. However, we have one that did not die but has been injured pretty badly. She will not move her right leg at all. I am a nurse so I have some medical knowledge but I've never "nursed" a chicken back to good health! Anyway, I can clearly feel that there is no break in the bones in the lower leg. But just below the hip area, there is "knot", I guess we can call it, that I assume is like a bone callus or where a possible break is. The chick does not move her foot at all but will pull her leg toward her body if I stretch it out. When she lays down (which is all she seems to be able to do right now). She stretches the hurt leg straight out in front of her. She is eating and drinking fine. We have her isolated in a chicken house by herself. Our chicks are our pets and we really care for them. If I can help her, I would love to! She's a silver spangled Hamburg and her name is "hamburger". She's my son's favorite chick! Can anyone tell me what I can do to help her?
