Welcome to BP.net! It's a great place for information and I'm glad you decided to come here. As far as getting hatchlings to eat, I can't really help there as I've never hatched out any BPs. So I'll let some other members deal with the feeding questions

I'm curious how you have your snakes set up. You said that Adrian was living with another male for awhile--do you house your snakes together normally? Or do they all now have separate enclosures?
