First of all I am a fairly new beekeeper. A few days ago I did my first spring inspection. Here's what I found. My two boxes were packed with bees, they had plenty of honey stores, they brought and were bringing in lots of pollen. They were fairly callm. What worries me is that I could only see capped drone cells. I did see larva but they were around the drone cells so I couldnt tell if they were workers. I also found several swarm cells in the upper box. I could smell a fairly strong lemon scent. I cant say I've noticed that before. I looked for the queen but did not find her. Before I finished I added a super and removed the entrance reducer to give more room. Any idea whats going on with the brood.
