This all seems a little odd...
So you have a gravid female ok..
You bought her as a boy???
This guy has alot of snakes, assuming hes a breeder, why/how would he not know
If he DID know why was he pairing Male to Male, Or pairing at all IF he doesnt know....
Now you just magically have a prego snake, I feel as if you paired and didnt want to admit because QT...
Just seems odd that you have a prego male snake, because the breeding aspect wouldnt match up.
