If it were me and I were just starting, I\'d mate both to all my females and see what I wound up with. That\'s pretty much what I did. Then learn from there from the results.
But Mike is right, be sure to toe-punch or at least find some way of PERMANENTLY identifying offspring from both males.
Ideally, you would want to breed full blood sisters to one male and say toe-punch them #1 and then wait 2-3wks, check for infertility, and then put the same females under the second male and toe-punch them #2. I\'d try to hatch at least a dozen of each and grow them all up to see what the results are.
Hope that helps.
God Bless,
