We are currently in the process of building our first coop and I am trying to figure out a few design features or details that I am hoping you all can help me with. So our coop is six feet tall, and it is 8ft(width)x12ft(length) it will have six windows three down each long wall for now, we may add one by the door so I can look in without opening the door up. The windows will be roost height so the chickens can look outside if they haven't been let outside yet.
What I am trying to figure out is how I want to do the roosts. I do want poop boards under my roost to help keep the coop clean, and I know I want the roosts about four feet up so that the boards are easy to clean. I am just not sure how long the roost should be, or if I should build a ramp up to the roosts? I thought of doing a two tiered roost/poop board, so half would be four feet high and then the other half would be like a foot and half or two feet lower for the heavier birds. Does that sound like it would work, or should I just do all one height? Also would it make sense to have the nest boxes under the poop boards? I am just trying to figure out the layout for all these things and am having trouble picturing it all and how it will lay out.
Also in case it matters I have eight chickens they are mostly heavy breeds, I have a few buff orpingtons, a couple Plymouth rocks, an australorp, red sexlink, Columbian Wyandotte and a salmon fav.
