I paired my male hypo with my snow female in the fall. I did not see any action between them and eventually decided to pull the male and put some more weight on him before attempting again. But I was wondering, when corn snakes breed the locks are very quick, right? So for all I know they could have locked (though for some reason I really feel like they didn't)

The snow female has never refused a meal and is still eating one large mouse a week. I have not weighed her recently. How would you know if a corn snake is gravid? With a ball python its easy. You see the ovulation or building and you wait for the shed cycle and so on. But how would you know a corn is going to lay? Is there a corn snake breeding guide that might have pictures?
