I found a ground squirrel with what seems to be 2 broken legs, 1 front and 1 back on the same side. I called a local squirrel sanctuary and they were not able to take it, but offered me a lot of information on how to help him out before I release him. What should I do about his legs? I don't want them to heal the way they are now. Will they be okay or do I try to splint them?
