Boston Bees
Bumblebee
Thanks all,
I bought a 4mm polycarbonate sheet, 6mm piece of timber for one side (bee space) and a 50mm treated roof batten for the other side (eke).
I will make a hole in the middle of the polycarbonate to leave the fondant above the polycarbonate (I think if I leave the fondant above the frames directly, that will block the bees and they will not be able to move freely above the frames).
Thanks
The problem with this plan is that the area above the crownboard is much colder than below it, so the fondant will go hard and become much more difficult for them to take down. Also, they are less likely to go up and get the fondant as the cluster won't be in direct contact with the fondant. I have found this repeatedly.
Feeding above a hole in the crownboard is more of a thing to do in late autumn when the weather is warmer and the bees are more mobile.
For emergency mid-winter feeding, I would recommend slapping the fondant directly on to the frames.
