Built a TPH last year and just had a call one week ago that someone had a swarm on a 3 rails fence. I was able to retrieve the hive in a transport box and put it in the Top Bar the same afternoon. One week later they seem to be doing good, have been feeding them they have been foraging and I am waiting to see the first signs of comb.
I do wonder how to tell if they are italian, russian, european bees. They are fairly gentle, they do come after me if I get to close to fast but only one or two at a time. I am hoping that once they have thier comb and get busy with that that they will not be as aggresive.
Anyway like the forum and the information on it.
