Just my personal opinion, but if I could do it, I would not hesitate to begin a Desert breeding project. I'd be very happy to raise those girls up and see what happens, and not be in any hurry one way or another. I absolutely love Deserts and their combos.
I think a lot of the "mystery" surrounding them is due as much to public perception as it is to reality. In our culture of instant gratification and information, we have less and less tolerance for the "wait and see" approach. Less trust for it as well. We've become an impatient and cynical lot. When something doesn't turn out exactly as expected right at the same time that all our interests have turned to that subject...then we are quick to assume that our current perception of that moment is reality and that the only explanation for the apparent failure is some vast conspiracy pulled over on us by "them".
I'll be happy to take any Desert females off your hands. Worthless creatures that they are.
x2! My foolproof plan is to win the lottery and then get a Desert pin when it hatches in the summer from a breeding a friend of mine is doing right now.
