kathyp, nice to know that it's at least possible! With the added warmth, do you think the queen will lay a few eggs? Or am I hoping for two much?
This nuc is actually almost directly behind where the original hive was placed. Hopefully, if one gets brave enough to head out, it won't get lost (more likely, it will freeze in minutes). I don't normally lean towards artificially keeping the bees warm during winter, but in this case, I'm pretty sure their demise was connected with the mite issue I went into winter with (my fault, which is why I was dripping). And now they don't have enough to stay warm on their own.
I wish I could pull brood from another box, but as kathyp said, it's cold up here and everyone is clustered tight. I could go searching, I suppose, but if I break the other clusters in this weather, the damage to the hives I open will be far greater than losing this small number of bees. If they keep going long enough, then maybe I can swap some bees around when a better opportunity presents itself. I'll definitely keep the suggestions in mind!
beee farmer, why do you say not to have too many stores? She does have room to lay, if that's what you are referring to, but the other three frames and nectar/capped honey/pollen.
Thanks, everyone, for the input, you always give me good food for thought!
