I have a female bp that weighs 880g. She is atleast 6 years old. I bred her 2 years ago, at 800g. I got 3 good eggs. One of the offspring is still very small, but the other 2 are bigger then there mom.. The smaller one is a male, I'm going to breed him to the mom and see if they are Dwarf balls? LOL?? Worth a shot....
