generally what is advised as the best and most effective way to start a small BP breeding operation is:

Get nice females first, good looking single-gene females or two-gene if you can afford. Female enchi is never a bad choice, or female pinstripe or female mojave.

males are generally cheaper, and reach sexual maturity faster. And you need one male for (opinions differ) 2 or 3 (or even 4) females. So once your females get mature, get a decent 2-gene or even 3-gene male.

if you want to go into recessive, lets say clown or whatever, basically you do the same: start with female het clowns, once they are mature get a visible male clown.

its jst the most cost-effective way to start i think. one powerhouse male and 3 single-gene females, thats just 4 snakes to keep, but can produce up to 3 clutches of eggs per year. and the money you invest in genetics goes mainly towards the male, where the genes are cheaper and the effect of the investment is tripled.
