I had one package of bees from last year that never really did much. Never really built up all last summer but enough to overwinter. I always suspected the queen never got properly mated well. Out of 4 hives it always lagged way behind. I decided that I was going to replace the queen this spring. I looked at the hive at the end of March and I still believed I should replace the queen. Well now I noticed that the hive has had a lot more activity so I opened the hive up a couple of days ago and to my surprise the hive is doing very well with lots of bee and on the verge of really booming. So now I am thinking should I replace that queen? Last year she seem to be a dud, but this year it hey get out of my way. I'm confused.
