I had to female levis this year put out 26 eggs between them....they can lay 14 days apart although 23-30 is more typical. They only mated once, and there was only one slug, they will pretty much keep laying as long as you keep the feed up to them. I fed them both dusted and gutloaded large roaches 5 or 6 nights a week, they only stopped laying eggs when I backed the feeding off. Be warned though, you have to find homes for them all.....
