This is a new one on me.. I installed a new package of bees on Monday and the queen was freed from her cage on Wednesday. I peeked in on Thursday evening and no bees. I have never heard of a package swarming but that is what it looks like. Only thing left was one side of one frame of foundation drown out and a small bit of pollen in it and about 150 bees, nothing other than that. Any ideas what happened?
