I inspected my hives today. One queen I noticed was rather fuzzy. I was laid up after surgery the end of last summer, so I didn't get into the hives for several months. This hive used to be pretty hot, but was just fine today.
My hypothesis is that the old hot queen was superceded last summer and this queen is still fuzzy because she's only a few months old.
Does this sound like an accurate assessment of the facts?
