single-gene females are quite useful, single-gene males are much less useful.
i would keep both females. if the spider is a hatchling now, it will be ready to breed in 2 or 3 years. male hatchlings are ready to breed after just one year.
so i would keep both females, and now you have one year to save up for a nice 2015 hatchling male, and go for a double-gene male, like maybe a lemonblast or something.
breeding a lesser to a normal is not a very attractive breeding. lemonblast to spider and lemonblast to normal is much better, the same with any other nice two-gene male.
Iv never bred snakes before. The reason why im taking it into consideration is to have that experience & then if i do breed, take it from there. Build it from nothing pretty much. Makes sense??
