Hi folks...first year with bees. Is this a sign of overcrowding? We bought a nuc May 1...split the hive in July. This is the original...we have a two deep boxes (one brood, one honey super). Its not a hot day...over cast with a potential for rain. Just don't know why they are hanging outside like this. No fanning bees, or very few (2-3). Opening is plenty wide...no issue with blocking the entrance. Bees are just sitting there.
