Hello We are relatively new to beekeeping. We got our first hive in September 2009 and another - saved from a dump - about three weeks ago. About a week after we got the dump hive, our first hive swarmed and the swarm disappeared, leaving a small colony behind but we didn't inspect. One week ago (about two weeks after the swarm went), we found a swarm in our garden, in a cherry tree beside hive number one. We think this came from hive number one again - they aren't as aggressive as the dump hive bees - or perhaps it could have been the first swarm returning although I don't know if that is possible... We managed to capture the swarm and put it in a "ruchette" as the French call it (mini hive with 5 frames - is this a "nuc" in English?). We inspected all hives today. The ruchette colony is doing really well, active and thriving but we couldn't find the queen. There seem to be some brood cells forming. The dump hive (had for 3 weeks) is doing well - we are replacing the frames gradually as they are all broken. They are quite a lot more aggressive than the first hive or the ruchette colony. Then we inspected hive number one (which has swarmed once if not twice) and discovered plenty of honey, about a half sized colony and about 5 brood cells over 10 frames and we couldn't spot a queen although we don't have that much experience. What should we do to help this colony reestablish itself?? Thanks so much for any advice!!
