Ron Brown of Devon (sadly no longer with us) came up with a solution to the problem of feeding Apideas. He filled cutcomb containers with fondant with a access hole in the lid and placed this "feed cassette" in the feeder compartment (it just fits). Because the container occupies most of the space in the compartment the bees are inhibited from building comb in it. Restocking the Apidea with feed is really swift / straight forward consisting of simply removing the empty cutcomb container and replacing it with a full one
