Some hatchling ball pythons won't eat?

Is it regurgitating, meaning it took a rodent all the way down and then you later found it had thrown it up, or is it just spitting it out? If it is spitting it out, then keep at it. I've got one baby that I had to assist feed more than ten times. It is now the best eater in my collection, eating every offering. Sometimes those slow starters turn out to be great snakes. If it is a true regurgitation, then it could have an internal defect that is causing a problem. However, I still would not give up. I've had a baby that regurgitated twice, then it started eating on its own and hasn't had any problems since. You never know, so keep at it.

What are you trying to feed her now? I would try mice and very small ones at that. I wouldn't just let her be so she passes since "in the wild not all survive", in the wild morphs don't normally get crossed, nor do eggs getting artificially incubated, nor do they eat Norwegian rats, nor do they sleep on aspen in tubs set to the perfect temperature. So if we can control pretty much all aspect of their lives why not try to control who lives and doesn't. I say you keep trying till you cant no more.

I have a female Cinny that will not eat without being jumpstarted (Assisted). She is just coming up on a year old and roughly 250 grams. She has only recently started to seem like she enjoys eating, but she doesn't seem to know what to do with food until it's in her mouth.

I havea pair of ghost bps that both wont eat for us we been force feeding ever since i got them, and guy claimed they were eating for him np.
I think I will see if i can find the parts(tubing) I need and try the yougurt on these to and see if works cause i hate to lose these ghost.

Thanks for all the help guys, and I meant to say she was spitting it out but, today she ate her first mouse on her own and I was so happy!!! Thanks again guys!
