Hello evanmancini2011,
When my queens get nanitics, I make a small feeding tray that will fit into the test tube. I’ve used small balls of cotton, now I use small pieces of sponge, I saturate one with water and the other with sugar/water and put them on the tray. You can also put small pieces of protein on the tray. Slide the tray into the test tube and replace the stopper. Blowing gently on them often makes ants retreat to the depths of the tube when you go to replace it. Timing is critical. Prepare a replacement tray ahead of time and act quickly to minimize escapes.
Your colony is still quite small and they can live with low humidity as long as they have drinking water. Feeding them in the test tube will give them time to increase in numbers large enough for an outworld.

My father always said I had ants in my pants.
