You can see the quick postage cost their brood very little:
They also seem to be using their major workers to shred up the cotton. These photos are all from yesterday - by today they're even further up the tube, and are now living in the shredded cotton. They will have to be moved, but to where? Should I keep them in a test tube, or move to an acrylic S?
They also need to be fed as soon as possible, but there's no way that's happening in the test tube. I also haven't a clue what to feed them - sugar water and protein jelly? Or do I give them seeds yet?
