I can't say I have much experience when it comes to young BP's not feeding but I did see a cool video on you tube. This guy had to assist feed a baby boa or something and he would use the legs of a small rat (few weeks old). It looked like it was a lot easier to assist the snake in getting it to start eating. I'm bust at the moment otherwise I'd find the link to the video but I'm sure if you Google assist feeding a snake with rat legs or something you'll find it. Good luck with your babies. I'm sure they'll be okay. keep us posted on what works or doesn't
