ours were not bought with the intent to breed them but that's what they do. i would have to guess they like it LOL. sometimes the male needs to give her a rest though. we have loved caring for them, my wife caught every one of he eggs as they were delivered (as a mid wife) all of the hatchlings went to friends homes and they know what their poop looks like when big and they know they will live 150 years. we love them and their habitat is perfect also with a concrete footing all around the perimeter.
i guess you have had a different experience with them then we have
so your concern is not for the mother but for the babies? being poorly cared for?
