I was at a local museum this weekend and they had an observation hive. The entrance was a PVC pipe, at one section was only 3/4" with most of it being 1 1/4 or so. The entrance tube went to the side, then directly up about 10 feet, then thru the outside wall.
My question is will a hive survive with a setup like that? I'd love to put an observation hive on the back porch. I don't need nearly that long of an entrance but it would be nice to get the entrance a bit away from normal porch traffic.
The entrance they have seems like it would be prohibitive.
