I had a swarm on one of my hives last week, and have noticed significant egg/brood reduction. I have heard egg production drops off after a swarm but am wondering if I should be concerned. This hive 2 weeks ago had 4 FULL frames of capped brood. I am wondering if it just takes some time to get things going again? There are no emergency, supercedure or swarm cells to be seen. Any opinions?
