Looks like I will get to build a coop for my mother in law. She wants a walk-in coop and plans to have 8-10 Hens. (before chicken math) Currently we are thinking about the coop in the Dummies book. Just wondering if anyone has comments or tweaks for this coop? I know that she does want me to build a porch onto the front. Also, she lives in the rainy area around Portland Oregon.
