I have a Camponotus colony with around 8 workers. I recently took them out of hibernation, and their test tube was super moldy. I had placed the test tube in a small take-out container for easier feeding, so I just put a second, clean test tube next to their first one. I did this with my other Camponotus colony and they moved into the new tube within a week, but these guys just don't want to move into the new tube. But here's the weird thing; they recently started moving their brood in and out of the original tube into the corner of the container, sometimes multiple times per day. The queen usually stays inside the tube, but I saw her in the corner with the brood at least once. I'm not really sure why they keep moving, the corner they're moving too is slightly closer to their heating coil so maybe that's why? I've included a picture to better understand what I'm saying. I'm just not sure if this is something I should worry about or not. Thanks!
