How often do you breed them. You don't have to breed them every few days to get a fertile clutch. I breed mine once every thirty days. Or until I see the female ovulate. I got a clutch of six eggs from one of my females this morning following this breeding routine. All of the eggs are fertile, however I do have one little bob egg. Of which Iam not sure will hatch. However time will tell. This method also keeps you from over breeding your male as well. I once thought that you had to breed them often as well when I first started. I hope this helps.
