Yes, I'm in Virginia.
This model is 4' x 6' with 2' sides, so the bottom would be 6' X 8' and the top 4' x 6'. There are two perches inside for a total of 12' of perch space, and 4 nest boxes (on the ends).
The idea for winter is to close in the bottom part with plastic so it's a double decker - top part with perches and nests and bottom part on the ground. I would bed both top and bottom, and enclose the whole thing in a 20' x 30' run.
Cheers,
N. Virginia
