it depends when I was younger I was walking with my brother and our friend, and we came across a red winged halk with a broken wing on the sidewalk, my brother and our friend stayed behind a watched the halk while I ran home to get my mom, she found a box, and towl and called the wildlife center, she came used the towl to get the halk in the box and then draped the towel over the box to help keep the halk calm, we kept him at our house until the wildlife people came to pick him up but them the halk was injured bad and was laying on the ground but alive, I think I woul dlet nature take its coarse for an animal with teeth however, they can and do bite when afraid, they could get me really really sick if i tried anything. it really depends on the problem and the animal.
