Hi Matt...just to get back to you on the dimensions. The chosen box this year has 12mm ply construction and about 28mm entrance. Who knows why they choose the ones they do. Hope you get more data for your investigations. This is the first year my birds have had such a choice. The patio box has been rooster in quite often and this is the only one attached to the house.
