They looked like they may be locked, but it's hard to tell from the pic.

As far as breeding different species and subspecies matters, it's not the best thing to do but it happens all of the time. Just make sure you're honest about what was crossed when selling them. I can't really tell from the pic but it looks like you're breeding two Bcc, so no real issue there.

People get more "upset" when subspecies get crossed and locales of Bci are crossed... even though they are all Bc subspecies, people want "pure" locale and subspecies. I like to keep them separate though and have Bci Nicaraguan boas and Bci Sonoran boas that I keep apart. It really doesn't matter too much if they aren't being released into nature.
