My newest ball is a little 6 month old het pied female... the breeder popped her and it left her with a big kink right above the vent. Unfortunately I didn't notice this until my wife pointed it out after we got her home. She can still pass <large> feces without a problem so I don't think eggs will be difficult either. One piece of advice I got from another breeder was to keep her on the lean, but muscular side since a fat BP will have more trouble passing eggs to begin with.
