I bought a female ball python a few months ago. She was about 1100 grams. I was feeding her about every week and she recently stopped. When I opened her cage today I found 4 eggs. I thought that she might be gravid but I didn't know for sure. I have never put a male in with her because of her weight. The guy said she was bred to an Albino before, but he didn't metion that he tried earlier this season. Could she have held sperm since last year? Is a breif encounter with a male enough or was he pairing her and dumped her off on me because of her weight?
