When I was cleaning the brooder today I noticed of of My chicks leg is bending strangely. It's bending back and to the side. I've changed two things. I've put up some roosts and changed to bedding to some puppy pads because the chicks where eating the paper towels. The joint looks swollen but she's still walking and eating and drinking well. I had just set her down and she had not adjusted her leg yet. She let me move it around, tucked in to her body and stretched it all the way out with some pain getting pressed up into her body. What is this? Something with her tendens? How can I help her?
