Finally got the nest done, and I still made mistakes. This one was the 4th and lacks the copper heat pipe that I just forgot to put in before the pour. I really should consider a check list, but that feels like work and I’m a slacker. I just whiffed one fully, then forgot to put magnets in one, then dropped one, after getting a glass cut for it.
So here now on the 4th one and they moved in ASAP, filling it with brood as I had and had not imagined.
These are phone imagines, I’ll rig up some better lighting and bust out the real camera soon for some beauty images with no heat cables.
Before:

This had to come apart, with the left nest off first, and then the middle one.
It was real stressful work as the colony is packed in there enough they just pour out of any hole I open like water, and the queen was currently in that last nest. So I needed to keep real close track of where she was to ensure she’d not A: fall out of the nest, or B: Get smooshed at a port hole when i’m trying to jam a tube into it. Fortunately she quickly moved into the next nest over when I started to disturb the nest. And then again when I started to disturb the middle nest.
So the queen moved all the way into the first big nest and was still there this morning.
Here is the new nest.
I wanted to provide as much flat space as I could, seeing them want to spread feeding larvae out next to each other rather than kept in piles as the non-feeding larvae and pupae are. I also made this one shallower than the previous ones. i noticed the depth was just a couple mm too far awawy from my macro lense to focus on. You can spot a couple smoother/odd spots inside on the back left area. I had a little sand collapse and needed to enlarge the tunnel space a little.
And here it is in place
And just after getting it al hooked up:
Here is blurry bad shot from this morning: They have filled all the spaces in the new nest with brood. I had imagined they would use the water tower room, but not all the rest of ti too, including the hall ways.
Here is the full shot from this moring, you can see the other nest chambers far left and top, where they used to keep brood have been mostly emptied. The first two chambers in the large first nest have also been mostly emptied of feeding brood now holding the eggs, tinyween larve still in flowers, and waking callows. And the pupae are in the big nest on a chamber right over the heat pipe back left side you can see the pile of white and yellow/orange.
Here in the largest nest where the queen moved to sense the remodeling, we can see both her and the serious pile of callows going on there. From just ecloased whitish yellow in the middle to all the light golden orange ones around the edge. I think they have reached a new production rate level. I assume we’ll see alates sometime this year out of them.
