Happy to help - although
@kinyonga is the expert to listen to. I took all of her advice as I was waiting for Ophelia to lay and we were successful.
Ophelia did not slow down on eating - eating everything I gave her. I keep a poop journal (pics of poop) and gave her a few more blue horned worms if I felt she needed them during the week. She was still active (almost crazy/pacing) and wanted to come out, so I took her into the sun whenever I could. From the time she starting digging, it was a month before she laid the eggs. In that month, I took her to the vet 2x and weighed her once a week. She was about 160+ grams around the time she laid - she is normally around 120 grams.
I did have trouble with her laybin. I had it properly set up, but the holes I had drilled in the bottom, sides, etc. were not big enough to drain the water (she has an automatic mister) fully, so when she dug to the bottom for the first time, she had 4 inches of water and quit. I was glad I checked. If I had totally left her alone at that time, I wouldn't have caught the problem. So I dug out all the dirt/water, drilled new, bigger holes and filled it all back in. I have never been in such an anxiety/panic as that afternoon. I was sure I had screwed it all up for her. And it was the longest month of my life. I had her cage covered, but kept the same schedule of auto-lights and auto-misting. I fed her as usual and scooped out poop at that time. I used a feeding bowl. She got big and clumsy at the end so I didn't want to risk her falling trying to catch bugs loose in the cage.
Other than that... I just tried to breathe and not stress. I wish I had set up a video cam, but maybe next time
Good luck!
