I found the problem with the hive that was pulling brood .. that we discussed in this forum:
https://beemaster.com/forum/index.php?topic=53245.0Here's a pic of what we were discussing there.
It was warm today, so I opened the hive for inspection. The queen is laying only drones. 3.5 frames of drones, in worker cells. I couldn't find her but i didnt look too hard. All the eggs were on the bottom of the cells in dead center, exactly as a queen should lay.
She was 1 of 2 queens that hatched right around Jan 1st of this year. I'm guessing she did not get mated.
The hive is small, dwindling in worker population, and the average worker was born around the 15th of Dec - so they are getting very old. I can't see saving this hive - by the time that the bees raised a new queen (if they could) the workers would be so old, and so few, that the hive wouldn't recover. So - I dumped them out. The workers will find new homes. Hopefully this answers the questions on this hive.
Comments and thoughts are always welcome.
