OK, so this may sound totally crazy, but I can't be the first. Small yard and looking for coop locations. We have a large covered patio (20 x 25), with a very solid tin covered roof, outside our living room. The surface is covered in unstained Saltillo tile, one side is the brick wall to the master bedroom, one side is a sliding door and 2 windows and brick to the living room, the other two sides are framed in with 2 x 4's and originally had screen wire covering them until my kiddos busted through them years ago playing toddler basketball. The ceiling height is 9 feet and it's got a north/east orientation.
How crazy would it be to put hardware cloth over the open sides, a thick layer of sand on the floor and some roosting bars and nest boxes for about 8 hens? It would be an open air coop but since most of the year in San Antonio is moderate to killer heat, only a few days would require any addition of clear plastic to cut the wind. I could add a cover and sides over the roosting bars for more wind break if necessary. The hens can also spend several hours roaming the yard and greenbelt behind the house in the late afternoon.
My big concern is any health hazards keeping chickens this close to living spaces, although we really never go out through this door or open the windows. Also sand getting in the house (though it can't be any worse than my husband's original idea when the kids were little - turn it into a giant sandbox for the kids).
I have been trying to come up with all kinds of coop configurations and it was my 12 yo who pointed out that we could make this the coop itself.
Thanks for the suggestions and consideration.
