The decision to confine them has always been difficult since it seems cruel. I've always wondered if others resort to this when all else fails. So you think I've just been lucky when the female actually completes egg laying. Very rare is it that I loose a female.They usually Finnish the digging g in the evening and lay the eggs when it's dark or almost dark. I do not recommend moving them back and forth. This is stressful an IMHO. It's a hormonal "thing" that tells them to lay or not IMHO so confining them shouldn't/wouldn't work unless the hormones are right. Just my opinion.
After reading your discussion regarding the hormonal aspect I think all confinement will stop. Thanks for providing this, and, being helpful instead of nasty.
