"All in all, it would be stupid of me to outcross for hets, when I have pairs of axanthics. I would think only an idiot would do that right off"

Why would you not outcross as soon as possible? It is an essential part of proving out how the gene is inherited. It is pretty important to do that. Take the "sables" for example. There have been hets sold yet the gene was never proven recessive and at this point, it most likely isn't.

Anyway, it would be quite easy to do the out cross. You can use 1 male for multiple females so it would take nothing to take one of your axanthic males and plug him into a normal female. This is a position that any breeder would want to be in this early on in the process of proving out a gene. It is actually the smart thing and the ideal thing to do. You would be shaving a few seasons off proving them out.

That's just my 2 cents.
