It depends on a lot of things, typically small female lay small and large females lay big, but even then, that's not always the case. 4 is a small clutch, I would say 6-7 is about average. There have been a lot of 11-13 clutches out there, and some larger ones of course.
Thanks for the input. Trying to figure out how big of a rack I should look to get in the next couple of months for when we try to breed next year hopefully so we are ready for the little ones.
This year all my clutches were between 5-8 eggs with the average being 6 but all of my females are still young, didnt have anything over 2kilos, I have seen females that are huge and will drop 10+egg clutches yearly. I have heard of a clutch of 15
