Mikada - I would definitely try to move the males instead. Unclewillie made a good point that I completely forgot about to be honest. If you do move the females instead watch them and if they molt put a male in with them so they can mate again then move the male back to the original tank. But I'm guessin with as many crawdads as you got it would be the same amount of work to move the males as it is the females.
Edit - btw nice pic Unclewillie. What species is that?

While I cannot comment on the genetics of this, I can say that I have seen a few 'blue' crays myself. But these were fairly large individuals in a mountain headwater stream (just below GSMNP boundaries) with blue coloration. I'd imagine it has something to do with pristine water - cold, clear, high dissolved oxygen. Same specied further downstream did not exhibit the same blue coloration.
Steve, If i remember right, it is Orconectes longirostris (longnose crayfish).
