I'm still planning and scrounging up stuff atm I couldn't wait any longer for the chicks though. right now I have two windows 5x5 that don't open like 16 sheets of plywood 3/4 3x3 1/2. was bins from work bought for 12 bucks. Looking for windows that open and roofing stuff know I'm going to have to buy the studs and 4x4's for floor. I think my favorite bird we have atm is my wife's it's a little grey one probably no bigger than my thumb.That's where I got mine.My son loves chickens so I scrounged up enough stuff to build a cooop and run and bought us a few.
