I seem to remember someone on Kingsnake posting a clutch of 18-20...I can't remember who it was or when it was but they showed pics and it was certainly a lot of eggs and they were all together so I doubt they could have taken eggs from a different clutch and put them in there. I think he even showed the female on the eggs? I can't remember but I know its been done. But from a 1500 gram female...I doubt it.
