How long can capped brood survive without nurse bees?
I cut 2 deep frames full of capped brood from a birdhouse and put them in a deep, and then I put the deep on a children's play set until nightfall. During the few hours I was waiting for the foragers and scouts to return, ants got into the hive box and started wreaking havoc. There were lots of dead bees on the ground in front of the hive, and not a lot of bee traffic.
I didn't open it up, but I cleaned up the exterior as best I could, and took the hive home. There weren't many ants running around the outside any more, and put it on my hive stand for the night, hoping the colony would survive.
Within a day or two it was apparent that not enough adult bees had made it, and the hive was just empty of bees, so I put the two brood frames into another, thriving colony.
Daytime temps had been in the mid-70s and lower 80s, and nighttime temps in the mid-60s.
Could capped brood have survived that? Do they need anything other than thermal regulation after they're capped?
