Some of my hives are foundation-less (at least, since last year).
As a side effect, I do have an increased number of drones in the hives.
Some beekeepers think that a big number of drones is bad since they would get less honey.
The hive in question is very strong (2 full deeps, 1 deep honey, 2 medium honey).
Well, today I noticed a lot of dead drones in front of the hive. Also, there were lots of workers killing them and pushing them away.
Now, this behavior seems normal and expected in Fall, but I never noticed it in July. I noticed another hive that has started doing it.
Could it be that the workers notice the high drone population and decide to get rid of some of them ?
