Update 1-28-2018 Two of these colonies are still doing well. The third is not doing that great. They only have three workers, and there seems to be something wrong with the queen. It's been this way for a few weeks now, and every day I'm surprised the queen is still alive.
I built another
Dirt Vase setup for the largest colony. I've had their small Dirt Box in the out world for two weeks now, waiting for them to move in.
I've had lots of trouble in the past getting
Myrmecocystus to move. Sometimes the whole colony ends up dead before they decide to move, so I want to make sure that doesn't happen with these.
You can see the pile of dirt they put in front of the hole, sealing it off.
I might just end up having to dump them out.
