I'm guessing you are really asking, is there some way we can fix the leg ourselves and not have to pay a vet? The best way to answer this, is to imagine you are at your friend's house and break your arm. Would you be OK with your friend asking online how to set the break instead of taking you to the doctor? Animals can't talk, and they instinctively hide any symptoms of pain or sickness, so you can't tell from looking that they are in pain. But this baby bird is in terrible pain. Their nerves and bones are tiny, but work just as well as our. In fact they are more sensitive, because birds must be able to feel vibrations in their legs if someone is sneaking up the tree branch to eat them, like a snake. So it is PAINFUL, and a vet will fix the leg properly and give the bird pain medication. Please find it in your heart to help the little thing.
