Thank you, to both of you. I appreciate it.
Kathy, I did look around and inside the flue.... BUT.... you might be right. If I remember correctly, there might be occasional space between the inner flue and the exterior brick. Not sure, but I will check that thoroughly... thanks.
Iddee, if I find/hear nothing today, that is what I will do.... advise them to wait a few days/week. I alluded to that last night, with them. They were pretty worried about the whole thing, and imagining that they were having their house comandeered by the bees, so they weren't sure they wanted to hear that answer
Your info on a new swarm was good to hear. I suspected that might be the case, but still have obscure (obscure to me at least
) details like that to learn.
