I did some searching but was unable to find an answer to my specific question (perhaps because I'm unfamiliar with the jargon and was searching incorrect terms).
I installed two packages in mid April. One colony has grown like crazy, has filled out the hive body, and is about 50% into one super. Considering they had to draw out the comb for all of this, I'm impressed. The other colony isn't doing as well. They have the hive body about 50-60% drawn out, but they are not making any more progress into the remaining frames. They have been maintaining their size and approximate population for well over a six weeks now.
So here's my question: could I/should I take a frame or two of brood from my strong colony and swap them with undrawn frames from my weak colony? At this point I'm just hoping the weak colony will survive winter.
Thank you all. Because of work, I am unable to join the local beekeeper club, and I don't know anyone who keeps bees and can give advice.
