I have a young BP that refuses to eat, she is 6 months old and still the size of a hatchling. Only time she will eat is if I force feed her, which I hate having to do, even then she regurgitates it half the time. I can't get her to put on weight. Her temps and humidity are perfect. Not sure what is going on, vet checked out with no diseases. Any ideas on how I can get her to start eating on her own?
