I have a quick question. The cotton on my test tubes looks pretty dry. The cotton ball itself is wet, but on the side with the queen it looks very dry. I've also noticed some of my queens stacking their eggs directly inside the cotton, as if they can't get close enough.
The test tubes are 16mm x 150mm and I fill the thing up a bit more than half way, then shove an entire cotton ball down. I've noticed there are large air bubbles now in the water section that weren't there before, so some water must be escaping (and being replaced with air). The last thing I want to do is try to move them, but I'm concerned they aren't getting enough moisture inside their tubes.
Am I overreacting?
