I have a Female ball python that I got back in Aug 05. I put her with one of my males and i wasn't able to see a lock up with him ,but ileft them together for a while so they could have done it any time. She has stop eating and doesn't want any thing. She seems top be getting lumpy from the middle towards the tail. Can I assume that she is gravid ? How long should I expect for the eggs to come out? Thanks joe
