See this is where the confusion lies with the female Desert thing. Nobody every said that Desert females can't lay. It's been said that they just don't do well...they normally die, slug out, or don't produce at all. But 1 in 100 doesn't really prove or disprove the original statements that female deserts aren't good producers.
I still have a small amount of faith that someone will do something to figure it out or breed them into some larger animals and make them better producers, but one female on eggs doesn't make me any more or less of a believer.
