Something appears to have happened to injure one of the large snakes that live in my yard. The family has been around for years and I've never had this happen before. It looks as though it suffered a skin injury that is healing, and a section about an inch long seems to be somewhat flattened in that same area. It allows me to hold it without complaint, and isn't moving around much. I can always walk out to the grass pile and find it laying on top or just slightly buried. The others are there too (I counted at least 8 yesterday) and they seem fine. Noticed the injury three days ago. Have provided a pan of water, and she drank very heartily when presented with it. No such thing as a snake-vet in our area. Ideas? Also, to what extent do snakes suffer form parasites? What about fleas, lice, etc.?
