My buddy had caught a swarm from his hive last week. He only has one hive left at his house (out of 5 going into last winter). He caught the swarm, made sure the queen was in the brood box, and the rest of the bees followed her in. He checked today (it was 8 days after he caught them). And, he not only found eggs but, larvae as well. Is this a bit odd? Plus this same hive may have swarmed 2 weeks ago (he was out of town, his wife saw a "bunch of bees" in the road but, by the time I got there they were all gone). His hive (the one we think the swarm came out of) also has eggs and larvae in it.
