This is my coop I built with the help of my nephew. I will be more than happy to answer any questions.
I am currently raising 9 Delaware hens, 5 Silver Laced Wyandotte hens and 3 New Hampshire Red Roosters. I have hatched out one batch of sex link chicks, I sell the hens and raise the roosters for meat.
I add these plans and photos to give you ideas that will work for you, not necessarily as blueprints. This coop works great for me, but makes no provisions for cold weather, artificial light or hen brooding chicks. Also, this coop is 100% utilitarian with no concern for aesthetics. Of course I live on 15 acres in the middle of a National Forest, with no neighbors in sight. A little trim work and color or siding selection could make this sub-division worthy.
