The babies have all had their molt I believe. I got a second enclosure set up with heat and substrate for mom which I plan to move her into in about a week but this behaviour is the coolest thing I've seen in awhile..
A few brave babies started to venture from her back. A few days ago I gave mom a huge super worm which she gobbled up quickly. I then put a bunch of small crickets in. The next day those few babies were hanging out near the opening of the burrow. I put another super worm in there and the mom grabbed it, killed it, and left it for the babies. Some came down and started eating.
Later some babies were Near the opening of the burrow with mom behind them again and a cricket went down in there. The babies quickly backed under mom, she grabbed the cricket and killed it leaving it for them.
Then today I put another super worm in there and mom grabbed it and started eating it for herself.
She clearly knows the difference between her babies that hang out in front of her and a cricket. I was fascinated that babies can run right under her claws and mouth but she ignores them and kills the cricket when it runs the same way.
They seem to be doing well. Most of the babies stay on her back and she rarely leaves the burrow so I can't see them all. The few that are coming out have already more than doubled in size and are changing color. They are now a yellowish color and you can easily see their little claws and tails now.
I'll try to get better pics. I cleaned the water spots off the glass only after I got these crummy pics.
This little one is eating a cricket killed by mom. You can see her huge black claw behind it.
