Even if his hets are all legitimate, that would put you at 4 males and 3 females, none of whom can interbreed and produce visuals of ANY of the recessive genes at play. To me, that would be like buying 10 bird feeders because they're a "great deal", but living in Antarctica so I will never have any reason to use them.
And I still stand by my warning about the "het genetic banded" assertion.
