That looks great. Are you going to put in a poop boards? You won't regret it, if you do. I have the open roost and ended up putting in a hammock type catcher for the poo. It is working but is hard to clean. This summer I will be putting in the poop boards covered in linoleum. Also any exposed 2x4 will get poo on them; That is if they are sideways. I want to cover all mine with a thin chip board to help with cleanning also. The less surfaces that are flat the better. I wish I had known this when i started. Please understand I am not criticizing. I love your size and ingenutity. Its built well too. Gloria Jean
