As stated before, getting a snake right out of the egg can be tricky, you properly should have gotten it after the shed, but what's done is done, so let's move on.
1. 6qt shoebox set up, with hot spot of 92-93*
2. Paper towel substrate misted often, until shed
3. Offer hopper mice to get started feeding
4. NO handling, at all until feeding consistently, only to change substrate
