A window was also cut in the door. This allows us to look in at the birds without having to open the door. Both vents and the window in the door are covered with wire cloth. Clear plastic is placed on both windows during the winter. The vents are left uncovered, for air exchange during the winter.
All plastic is removed for the summer.
Once the house is done it needs to be furnished. On these nail whatever is going to be used for the roost. Just inside the door, on the front wall nail the nests. This location makes gathering the eggs easy, just reach around and pick them from the nest. This will allow space for a water fountain to be placed under them.
