I have three hives in my backyard in the SF area. Today is a beautiful 60 degree plus day so I took a look inside. Two are booming - lots of bees and plenty of stores. The third is very weak, with a small number of bees on just two frames (maybe a fist sized ball at best). I saw the queen, and there was a small amount of caped brood on one frame (maybe 20 cells). Hive is a double-deep. I noticed a bit of spiderweb at the top of one frame, maybe moth?
What if anything should I do to help save it?
1) Do nothing, see what happens.
2) Put the bees into a 5 frame nuc so they have less space to keep warm. Freeze the frames with honey.
3) Put some bees from one of the other hives into the weak one
My thought is to do #2 as #3 might weaken my strongest hives. Sound right?
thanks and merry xmas!
