New rescue

Well a neighbor who knew i had snakes is giving me his snake that he doesn't want. It was his daughter's and she went off to college. Snake hasn't eaten in 3 weeks he says he's in shed and is in bad shape. So i need help. Given the state that i may think he may be in what should i do first. I plan on cleaning the tank the guy is giving me and setting up the heat and and humidity the best i can. Should i feed him fuzzies or just a normal size mouse? I'll take pics as soon i get him tomorrow. I hope he is ok.

3 weeks is not very long to have not eaten. I would set it up with proper temps and humidity and once it sheds, offer an appropriate sized prey item. I would wait 1 week before handling or feeding as well, to let it settle into its new home.

How old is this snake? How long did your neighbor have him? The reason I ask is because most BPs move past mice and on to rats pretty early in life.

He hasn't said how old or how big....the way he describes him i'd say he's about 2 ft long if that. I'm going to get him in a few minutes. Got a spot for him all set up.
