We had the opportunity to by a nuc last night (Italians). I have been watching these new guys all day. The new hive had about a pound to pound and half of bees. We installed a frame of brood only(no nurse bees) from each of the other two hives (one Russian hive, one Italian hive). After a while I went out to look and I saw a lot of activity. Yup, the Russians were flying around, going in and out. It looked like an invasion! I though Oh ho! I saw some fighting but after the whole day I see only 8 or 9 bodies on the ground. To me it looks like some of the Russians adopted the new hive and are getting along with the Italians. If so, we went from 2 healthy hives and one nuc to three healthy hives in one day! lol This is our first year. Does this sound like normal activity or do I need to worry?
