Re: Can I move a whole hollow branch?
I would follow Adrian"s advise. I have removed several from trees with good success in nice weather. I just had a call last week when it was in the 30's-40's about a tree cut up after a wind storm that had a hive in it. The tree service had cut it into 3 sections before they relizied what they had. The bee reclustered in the bottom section with brood, but did not survive long. Even if you carefully cut the branch in lower temps, they will break cluster to try and defend their home, and pay for it.
I'm like the weatherman- right about half of the time.
