Hey everyone, I'm a first time blood owner with a little problem.

My new snake arrived thursday. He was very very cold and lethargic when I pulled him out of the box, but he seemed to move around ok when I warmed him up. When he arrived he was deep in shed.

I put him in a 15 qt. rubbermaid and left him alone for a couple days. I pulled him out this afternoon and he was really lethargic again. He didn't move much and didn't react to me at all. He also wasn't pulling his tongue all the way back in. He's let his tongue just hang out and maybe flicker it a bit. The "fork" in his tongue was stuck together as well.

This evening I checked on him and he's still acting weird. He's very active, moving and rubbing along everything in his cage. He did his very best to bite me as well.
I'm assuming he's trying to shed, but he's also flipping over on his back and getting his head into odd angles. Sometimes when I look in there he'll have his head and neck upside down, or he'll be looking straight up and just stay like that for a couple seconds. But at least his tongue is acting normal now, and it seems to be back in it's normal shape.

His warm side is ~88, cool side ~78. Humidity never drops below 60% in the room he's kept in. Right now it's ~80% because he's shedding. He's got a water dish with fresh water, and two hides.

Is this normal behavior for bloods and I'm just being paranoid, or do you think something's wrong?
