Update: Half of the bees are in the medium I left stocked with 1/1 sugar water. Half are back on the tree. Scooped more off tree and put in box. Added a super on top and more syrup as it's all gone. I'm unsure how much disruption they can take before f'ing off. I kid you not, 100 000 strong. Quite sure they did not come out of someone's box. This is a wild colony. If I manage this I will have scored my largest win yet. Also I have met my new neighbour in the process and he is gonna be a bunch of fun. His man cave has 6 plants, 12 ft screen, full kitchen and a stocked fridge.
