There is a deer that keeps appearing near my backyard and it has a broken leg. It ran away and was only walking on 3 legs. The leg that was broken was swinging around and I don’t know how to help it.

You can call Aark, and they may be able to give you some direction about capturing the fawn. They do not have the resources to come get the animal but will care for it if you can get it there.

Aark don't really pick up wild animals. They will take them in if you can get them there. You can call 911 and they may be able to direct you to someone who can help the deer, but most likely, it will have to fend for itself.
