This is interesting. My new pied girl seems to be pretty mellow and is a great eater. She will take live or FT, and if I leave FT in the cage, she eventually will eat it overnight. I'm doing my best to only buy good tempered, well-feeding snakes in the hopes of getting babies that eat well and have nice dispositions. It's easy enough with BP's to find sweet snakes, and it seems most breeders are able to condition babies to eat well. For the most part, it seems like my snakes act a little different with certain people, so it not only depends on the snake, but the people interacting with them as well.
I've heard about duck billing and kinking. It's too bad to see that happen, but most good breeders seem to not have problems finding a good pet-only home for them, or keeping the oddballs themselves!
I'm wondering if most of the rumors are from when there were only a few examples of each morph, back when the clowns/pieds/etc were imports fresh from Africa and more prone to wild caught behaviors.
thanks for the responses!
