Ok, a bit of the history, then the question...
I am "fostering" 2 ball pythons for a friend of a friend; he stated that he tried to breed the normal female to a male mojave over a year ago (he wasn't sure when), but didn't witness any lockups; I go in to check on her last night (she's in full blue-eyed shed) and she is laying in a perfect coil, except she is on her back (!!!).
The info from him isn't really reliable, he's having relationship problems (hence the "fostering") and I'm wondering...
Is it possible for a female to hold on to the sperm plugs for a loooooooong time? She is ENORMOUS, slightly triangular shaped (ridge-backed), and continues to lay on her side or even fully inverted.
Is it possible that she is gravid this late in the season?
