The new big queen has added a few more eggs.
She seems to move them between the back of the chamber and the front glass.
I think to get the right level of temperature. Also, the glass may collect moisture and be at the right temperature for the eggs.
The black ants have spread the brood to the left side of the formicarium.
They have also placed some up top & in some tubing.
The new batch seems to be an even larger number than the previous one.
