I noticed the OP didn't dispute the statement that was made about housing the snakes together, but also (unless I missed something) I don't think he/she said that the snakes were housed together -- just that he thought he had two males.

It's highly unlikely, but it could be that he made a new purchase and somehow got a gravid female. Also, isn't it possible for females to store sperm and to also just lay blanks for no particular reason?

Yes, you were probably right -- he probably is housing them together, and it obviously ins't a good idea. But, maybe we should be sure about the facts before we slam somebody for their husbandry skills and accuse them of having half a brain...

Off my soapbox...
