I've been perusing the Coop & Run design threads for awhile now and I read a nifty idea on how to build the roosts so you can clean under them easily. They made the roost a ladder-type roost at an angle to the wall and put hinges on it where it touches the side wall so you can lift it up and out of your way. There's a hook on the ceiling to hold it up so you can clean under it with ease. I'm planning on using that design in my next coop. I tried to find that thread, but I couldn't.I'm still decided how best to make the roosting area without making it difficult to clean or walk inside.
Oh and great coop, BTW. I envy how quickly you can build one. Can't wait to see it completed.
