New snake struck and then laid out on back

He got held an additional night at the post office as well, so it’s been a little bit of a rollercoaster with him already, and I’m being a bit of a worry wort I guess.

Are you in the US? Snakes are not mailable through USPS so any breeder sending them that way should be named and shamed imo. That is not a safe or legal way to ship a snake which has me concerned about the breeder quality and care previous to getting to you, it sounds like you just very recently received him?
