Nest week's forecast looks like upper 40s and 50s.Not too bad for making nucs if you don't dilly dally and there is not a lot of cold wind. We have made them at 42F ,2 brood,1 bees,1 honey and an extra frame of bees shook in to help keep them warm.
The queens will do just fine in the battery box for a week or 2. We feed them a chunk of last years comb honey as needed and let the attendants out to cleanse every day or 2 if its nice. Amazing how they will all fly out like a swarm and disappear and in 10 minutes, all of them are back in the battery box with the queens, happy as clams.(i am the reason the battery box says do not use to store queens!)
Lloyd is right. You hafta take queens per your order. Ours are coming the 16th,ordered last labor day.
