all goes by quality
bees start as low as 350 up to 700 depending on colors, size, sex. Proven breeders will get more.
Killer Bees will fetch depending on same above of 800 low- 1500+.
All depends on size, feeding, quality and sex. Always pick out the best example of that morph if you ever breed it. I cant stand breeding low quality browned out snakes just to produce more to mud up the gene pools.
