The colony is doing really well, alot more ants and the nest is pretty crowded now with how many ants there are. Their appetite is alot bigger now and they're constantly forming pathways searching for food. The nest is also noticeably bigger now, they've dug a chamber at the bottom of the enclosure which they've stored most of their brood inside and the amount of brood overall has increased. Their nest is now about 1' deep with tunnels now along one side of the enclosure and looks as though they will be digging tunnels all the way around the setup. The tunnels they started digging now are just over 2' long so I was impressed to discover them last night when I took a look at the nest.
The nest as of last night.
I didn't realise the flash was on when I took this pic but the ants didn't seem to notice anyway. To the top left of the soil those are mould spores not clumps of brood, I was worried when they first appeared a while ago but the ants have just sealed them out of the nest.

The new chamber,

They also found their way into one of the artificial nests a couple nights ago, but the next time I looked they had sealed it off after using it to dump soil.

And one of the many majors,

Thanks for reading
