Our two packages of bees came in on April 11, 2013. I took my daughter with me to install the packages today, April 14, 2013. Temp was about 52° F with winds 10mph.
Everything went well. Duaghter took care of the queens when i shook the bees in the hives. Got a bonus of one queen being marked. No stings, and this install was the best so far. Very happy with the way things went. Both queens looked nice and healthy. Just have to wait a few days and check to make sure they were released.
