I started this year, and have three new hives a couple of feet apart. The two outside hives always have many bees sitting on the "front porch" and much hectic activity but the one in the middle has only bees coming and going (two or three every five seconds).
The one on the left was two swarms united (paper method) and the one on the right was a Package. the one with the least front action was from a nuc donated by a local beeman and was, I think, my strongest hive. All three have supers being filled with honey and so I haven't looked at the brood area lately.
My question is -- Is the relative lack of activity a warning that some thing is wrong in the colony?
