Update 3-29-2019:
Some good and bad news to report: Sigyn continues to thrive. She has four new workers about to eclose and should hit 20 workers very soon. They are feeding very well, and I'm glad to see them using the byFormica liquid feeders for nectar and plain water as needed. Believe it or not, these gals are outpacing even my Tetramorium in terms of growth and voraciousness at this early stage! It certainly helps that I've learned from so many mistakes.
On to the bad news: my two slacker queens, Frigg and Thrud continue struggling. Frigg got up to three workers, but I found one curled up dead today. My only explanation is that the nectar I gave them on Saturday must have dried up, so she starved. I blame this on the fact that her tube was still taped to the other new tube, but she refused to move. This obviously made feeding harder. I gave up today and forcefully moved the colony and brood into the new tube using a woodpecker feather. Dumping ants is against my philosophy of ant keeping, but I guess it is necessary sometimes. I got out as much of the tiny eggs as I could with the feather and put them in the new tube. Hopefully, her two slacker workers will find them and arrange them well.
There were a few eggs I couldn't get out of the old tube easily, so I put the whole tube in Sigyn's outworld as a kind of brood boost. Hopefully, some of her workers will find them, and luck will favor the vigilant!
