Could screen be used to separate 2 nuc colonies in a single medium 10 frame box? I have seen where folks use a dividing board that separates 2 nucs in box. However I was wondering if a screen separating them would be beneficial in the winter in terms of letting the 2 nucs cluster on the dividing screen and thus sharing heat better in the winter and maybe allowing better moisture ventilation. Staple a section of aluminum window screen between frames 5 and 6. Or would the pheromones from the 2 queens interfere with the colonies? I could/would stack a 2nd medium of stores above the nucs divided with the same screen. Thank you
