We are brand new to chickens and will be getting 6 pullets this weekend. We will eventually build a 'real' coop, but we need to figure out exactly what we need so are starting small and I'd like to repurpose an armoire initially. Our main area is a 13' x 12' slab attached to the garage. We plan to use 1/4 metal curtain around the 3 open sides and have the coop inside in the slab. My initial idea is to put this armoire about a foot from the side of the garage and have a ramp secured to the garage one side leading to the back of the armoire where the opening is. The front doors would stay closed, but I can open them for cleaning and egg collection. I would cut ventilation holes on the sides that can be closed if need be. My main question is how should I lay out the interior? Should I stack nesting boxes on one side or along the bottom with a roof/shelf so they don't get pooped in? If I stack them, should I start at the bottom and stack 3, or should I leave the bottom open so they can run the length of the bottom and only stack 2? Do any of you with experience have a better idea for me? If it matters, we're getting 2 Ameraucanas, 2 Australorps and 2 Silkies. Thanks in advance!
