If I am considering feeding dry sugar (on newspaper, a.k.a. the "Mountain Camp" method), do I need to put a spacer or an empty super or something on the top of the hive now? I do not want to create too much empty space. All I have to work with are shallow supers and shims that are essentially inner covers with the center cut out. Also, when you open to add the sugar, how do you keep from chilling the bees?
