I have an albino bull snake that has been huge for over a week now. She looks like she is ready to explode but still has not laid any eggs. The other female that shed the day before her laid her clutch 10 days ago. Yesterday she expelled some white/yellow liquid that somewhat resembles urates in her lay box. She is alert and tongue flicking. At what point should I worry about her being bound up? She is a thick 3 year old girl so she wasn't bred young.
