I have 2 additional hives, due to swarming this spring. They swarmed the end of April. I don’t know if this is useful to you, but thought I would mention it.
RESPONSE – We will hopefully capture this in our next season’s survey, if you would return and provide information next spring. . Our year is April to April. We have had several April swarms this year – more than normal it seems. Trust the colonies do OK.
