I am a first year beekeeper.
I went out to view my hives today and one is unusual. All have some bees going in and out, but the middle one has a large cluster on the outside of the hive.
We are in Central California. It is a beautiful day here (65 degrees, sunny, no wind). There is alfalfa growing on the other side of the irrigation ditch, 100 yards away.
Is this something I should be concerned about?
