The babies we brought home... they grow so quickly some of the coop framing, window in the back and vent on the side the left side of the structure is a shed, the right side is the coop, every wall is insulated. they finally get to move out of the box and into their new home they like to sleep all together in on of the nesting boxes pre-siding, most of the supplies were reclaimed, habitat for humanity, and surplus materials. not sure if chickens like her better or if she likes them better-hours of endless fun, and she can get them back in the coop the easiest siding was all given to us from a builders' leftovers. they later got a better play structure, but this temporary one worked for a while. the top of the nesting box opens up for quick cleaning and then front opens for egg removal This is looking inside the coop-shed door. We get some cold weather, so I wanted entry to the top (birds sleep) and bottom (food water) to be from inside the shed. This is the top this is the bottom-I can refill food/water from either this way or around the outside from in the pen. this is the shed side, not organized yet, but eventually will get shelves and organization looking through the door into the shed side our girls home-we let them have the whole yard when we are around, they do poop a lot though, so sometimes it is nice to keep them in their pen.
