I guess he is going to need to add an UTH and get a stronger suspended heat source.

The reason I believe it is skinny is simply because of it being so cold for so long, although I think it may have to do with the snake too internally. Normally snakes that naturally brumate or go into reduced activity don't loose mass this rapidly. So it may have a genetic abnormality that has resulted in an accelerated metabolism of body mass. If this is true and he does get it eating I guess he may have prevented natural selection (genetic defects resulting in an animal dying to keep the bad genes from being passed on).

The toads are as healthy as the area around here allows them to be. If the snake doesn't eat the toad he lets it go after 2-3 days.

I am going to recommend that he increase temps for the next week or two and if that doesn't work I am going to recommend that he just save and fork up the money for a CBB Eastern Hognose - which may be better if he gets one that's on mice.

Also it could be dying from chemical poisoning because he found it right after a lawn service put various junk chemicals in his neighbors yard.
