I have read a little here and there in this post but it seems you have trouble with moving the colony to a proper setup and I thought I should add some of my experience here. So I had a similar problem but I was about to hibernate all my colonies anyway so I had to make sure that the setup is clean. the only problem was that the colonies probably wouldn't move too quickly so I somewhat forced them.
I did a manuel moving before with moving the eggs with my tweezers (2 out of 20-40 eggs were destroyed by accident but better lose 2 than the whole colony.
So what I did is: I prepared a new testtube (for my main colonies with a seperation to create a small chamber for then colony. Next I moved the queen first by connecting both testtubes with tubing and then I made sure the testtubes were like mouth to mouth. Next I turned that setup to the queen either lost grip and tumbled down into the new setup. Next I closed the queens testtube and put her into darkness to avoid as much stress as possible.
Then I too a small plastic bottle and did the same with the testtube to move from. I used some more force to get the workers and the brood inside of that bottle and then after they were all in there I connected it with the new testtube so the workers could migrate to the new setup in peace. Since I had a couple I had to do it a bit more forcefully but I kept them a bit warm and in the dark for a couple of days to relax and then I had put all the testtubes into a box with some cloth to protect them and then into the fridge. The box is to avoid the light from disturbing the ants and also to move them all at once.
I think I will have to do a futur video of how I emergency moved them. Funny thing is I did the same with my Messor barbarus after I removing all their seeds first and the colony moved out super quickly
I used the light technic on them.
Anyway I hope this helps you.
Doing some proper research is the best way to start an antcolony. After the research you can still go and fetsh a colony from one of your local GAN-Farmers.
