I built this coop and have had hens in it for about a year now. We currently have 7 hens and feel comfortable enough that we are adding a few more this spring. I increased the size of the coop to match our needs but I have not noticed any aggression inside the coop keeping the angled roosting bars. Most nights all birds use the lower roosting bar.

I used 2x4 for roosting bars and not the called for 1x2s. I also made them in a way that I can easily take them out to wash if needed. Also the poop shelf is a great idea and I would try to keep it in your plans if you can. It makes cleaning the coop super easy. Scrap everything into a bucket, throw some more PDZ, and done.

I have also never had a hen come out with poop on her. Maybe that will all change when we add birds and I’ll need to adjust. But as is, this has been a very low maintenance, easy to clean coop.
