Size does not appear to the issue here. One of my biggest females was 6 slugs 0 good eggs, and my smallest just laid 6 good eggs with 0 slugs. I also use belly heat for what its worth.

Im kind of just chalking this up to luck of the draw, with the possibility of them being new additions adding to it. I also just had another clutch last night with no slugs my odds arnt looking as bad as they were a few days ago.

I would still like to know what other peoples odds on slugs and slug outs are and if they notice the same females dropping slugs every year.

Thanks guys this has been a helpful thread for me.
