So last week (exactaly) I got my first waterfowl in the mail (1 cayuga drake, 2 cayuga hens, and a pair of brown chinese). School get out tomorrow and I was looking for a project. I decided that I wanted to build a coop for my birds (along with a couple of planter boxes). So I want some advice about sizing, materials, etc. And if you guys have any coop plans that work well let me know. Oh and I also wanted to make it a hinge top house, what are your thoughts about this?
