I opened my hive of Russians Easter Saturday, and it was doing well. Plenty of capped brood, fair amount of eggs, and filled with bees. A week later, my wife heard a swarm in one of our pine trees, and before I could check it out, it was gone. It didn't look as active the last week or so. I opened it up, and it appears to have swarmed. Little more than half the bees, very little capped brood left, no eggs. Couldn't find the queen. When I saw her last year, she had her marking cleaned off off, and it's hard for a 3rd year beek with bad eyes to find. Should I see eggs yet? (I know they are microscopic at first) Could the hive have swarmed without a replacement queen? I have a nuc with a hatched queen from a swarm cell on a frame I pulled 2 weeks ago. What procedure should I use to requeen the hive? Can I just pull a frame, and replace it with the one from the nuc that she is on? HELP!
