Hey.
25°C have proven to be working for me and some other keepers. I do offer Honey outside the testtube, which i blocked up with some dry sand, so if she feels like it, the queen can go for a walk and look for food. dont forget to block the tube from all light COMPLETELY, not just the back part or whatever, i see this done wrong a lot of times.
Brood developement is slow, ammount of eggs produced is rather low. My queen arrived with around 5 eggs, now, after 2 weeks passed, there are a few more, and i discovered 2 larvae. Not expecting big changes anytime soon.
First genereation workers are probably going to be rather tiny.
