I have (about) 2 month old goose. She hurt her leg. I thought she just twisted her "ankle" so I put a splint on her foot for a couple days. When I took it off, she babied her foot and started walking on her "knee." I think she fractured her knee by walking on it. It's now very swollen and it looks like there's a bone issue going on. Should I try to splint that area to force her back on her foot? Should I let her walk it off? Will I have to put her down?
