Ouch...that tail looks nasty! Doesn't really look like a bite wound, but I suppose it could be. Looks more to me like multiple old stuck sheds were left around the tail and they cut off the circulation. That's just a guess, though. As for the limpness...that does NOT sound good. Maybe a spinal injury? I would DEFinitely consult a vet about that and would not consider breeding her without a confident vet's assurance.

Did you know about the retained eyecaps and messed up tail and such before you bought them? I'd question any breeder who would send out snakes in that condition.
