Swarm in October?
I opened one hive after a month and a half without checking it. I found two open queen cells and almost the whole colony was gone. My original queen is still there, and theres a lot of honey. Even though our winter is very mild (San Diego) I don’t think they’ll make without combining or getting extra work force.
But my question is, what could’ve happened? It was a strong hive and there was still two empty frames on the brood chamber. Is it normal to have a swarm in October?
I’ve been doing some work about 50ft from the hive, with a log splitter and chainsaw, could the noise have stressed them?
