I have been using 6 bee cozies for the last two years. My brood chambers 
have a 1" hole about three inches above the bottom which provides an 
entrance when the bottom board is closed with snow or ice.
A long screw or nail is used to hold the bottom of the cozie above the hole. 
I find it helpful to put a 16.25" x 20" x 2" piece of styrofoam above the 
inner cover as the supplied piece of insulation is not enough for our 
winters. I do not use top entrances in any of my hives - I have 35 -  and 
they seem to winter well.
