I have a question to the experts. I have had a hive that has always been a little aggressive but manageable. I check them 2 weeks ago and noticed they were more aggressive then normal and also notices that the brood that had emerged had not been replaced. I decided to give them 2 weeks alone time to settle down. I check again on them today and they swarmed on me and I could not see through my veil within 5 mins. I got all the way thought the hive and could not find any brood, but did find capped honey in the brood area. I am guessing queenless. Any thoughts?
