If you've only had them at 87 and 93 for a day or two of course you won't have eggs. Remember to only heat a portion of it, don't give it a wall of heat. That's not good either.
Wait a week or two. Be patient, relax, don't stress it. You've only had that colony a 1-2 months? It's Winter, they will not explode in growth during this time. Don't force it.
I have them in a ghetto incubator, made with a cardboard box with a heat lamp. Current temp is 87 degrees and yesterday it was 93, but still no eggs...
I have the lamp on top to the box, clamped to one side. Is that what you meant by a wall of heat? Also I got my heat bulb, but it seems cooler than the last one, and the thermometer reads 71.2 degrees.
Thanks. YsTheAnt, you saw their was a nestmate filled with sugar. I haven’t gave them an apple though
