I'm going to be building several nucs this spring. I'm going with a standard scaled down deep design with a bottom board instead of the one piece Coates design. For covers, I could make a scaled down telescoping cover and inner cover, or just go for a migratory type cover. In choosing between the two, is it really a matter of preference like it is with the full size hive, or are there specific advantages to one or the other with a nuc due to its smaller size?
