This might seem like a very obvious question, but never hurts to ask, right? My dad and I started keeping bees this year after taking a short course at the U of MN. We only have one hive that we started from a package we got in the spring. Our queen was strong with a good brood pattern, filling out 3 deep hive boxes. Recently, however, we've noticed that there is significantly less brood as well as queen cells forming. I've read that swarm cells form near the bottom and in large groups. I've only noticed a few, usually near the middle, which makes me think they are supercedure cells. My question is, is it normal for brood to decrease as we near the end of the season? I am from Minnesota, and the summer has been on the cooler side. And if the queen is weak, and they are trying to raise a new one, should we let them? Thanks for the help!
