I have seen double screen boards used while helping at our local bee yard and like the idea but wonder why there needs to be two screens. Maybe I am missing something on the purpose of the thing but as long as there is screen to allow warmth to get to the upper boxes and an entrance/exit for both hives isn't that enough? I am thinking about making my own so this question came to mind.
Thanks in advance.
