Rooster box measurements!!

[nanette7fl]

I am thinking about soundproofing on of my nesting boxes for my rooster. Here is a picture of my rooster and 2 pictures of my coop. The coop has 5 nest boxes. 2 small and 2 large. I was thinking about taking one of the large ones and putting vinyl sound proofing all around it. Then I was going to make a door (with sound proofing also). I was going to but vent holes in the door and keep a slit on the top of the nest box for ventilation. He sleeps in a next box at night right now. He is 6 months old.
