I too would give them till Monday or Tuesday to respond just because of the long weekend.
Then what ever wait time after that is up to you.
Also this pic the breeder sent you may show it, I cannot clean it up enough to tell if its the tip of the tail or the kink (under enough zoom to tell it pixelates too bad)


Next question is, how attached are you already? Are you going to worry about what happens to her if he gets her back? Some people treat their animals as just dollar signs! (I had a partner of mine want to breed one of my APBTs that was in the middle of heartworm treatment just because she was in heat!!)

Third and final, Is it possible to get an x-ray done NOW just to see what is going on inside her? I dont know what it takes to x-ray a snake but it would help you to inform yourself and see if there might be signs of injury and not genetics.

I wish you luck and please keep us informed of the outcome.
