I once saved an abandoned fawn. It was around my place, and alone for four days, before I knew for sure it was actually abandoned. Then it was sufficiently starving to death to walk right up to me. I put it in the fenced part of my yard. I called local wildlife agencies to find out what I should do. I was told by all of them to just put it back in the woods and let it die, and of course they all had to tell me it was the law, and I could be in legal trouble if I didn’t. I didn’t. I eventually found out they can be fed goat’s milk. Got some from Winn Dixie and fed it four times a day with a bottle, for three days. I found a wildlife rehabilitator some 75 miles away, and took it there.
