After reading the text by Jim (sawdustmaker) quoted below on another thread, I have decided to purchase an observation hive. Now I have no experience with this type of hive and there are many brands for sale. Any and all advice is appreciated except for price. Per administration rules, please do not post price. Also there is single window verses multi window, which do you prefer. Thank you for your input.
"A few years back I put a fat honey frame in my observation hive and it was too close to the glass. I did not realize it until we put the hive back inside. It took the bees two full days to cut it to provide bee space. When they were done, it looked like a laser cut it and the cells looked perfect. It was pretty amazing."
