Hi everyone, I have been looking around the net trying to find what's healthy vs not healthy to look for in a newly hatched Ball Python. Just a few questions for you guys! TIA!

What does a healthy looking umbilicus look like once out of the egg? Should there be anything protruding from the baby at all? My first one out of the egg has what looks like an umbilical cord stump like a human baby, but sometimes it looks a little bigger and redder when I check in on him.

Should I put a bowl of water in with the hatchlings right away, or wait a day or two? This is probably an obviously dumb question....

How should a hatchlings' activity level be? I just want to make sure I'm not missing any danger signs... Should they be moving around quite a bit, or being still?

Thanks so much, and if anyone has any more advice or tips, I'd certainly appreciate it!
