We finished building our coop! It's 7' square with nesting boxes on one side and the door to the ramp on the opposite side. It's a single slant roof with the 4' high side where I'm leaning in the 2 foot square door to take the pictures, and 6' high on the other side with the window. The entire coop/door/boxes are insulated. I've included pictures of our current roost setup and am trying to ask about the distance between the roost and the poop tray that I want to put in. We tried the roost here (see pictures) at about 18" off the floor and 18" off the wall, with boot trays underneath. The girls have been here 3 days and they've scratched the straw into the boot trays, over the sand I put in the trays, so it's made sifting poop out somewhat of a pain. If my lowest ceiling above the roost is 4' tall, how much space do i need between the roost and the poop tray? I've read that you need to have the same measurement of roost height and distance for them to fly down. there is also a vent on that 4' tall wall side, up near the top of the wall about 4" down from the top, so I would not want my roost higher than about 3' because they would catch that breeze. Also, they would need 3' to fly down before they crash into the nest boxes. I need to make the poop trays high enough for them to go under so they can get outside. Thanks!
