My birds are free roamed 24/7 but do have their area as well... it is a 12ftx30ft run with 4 small coops inside of it. I have 16 chickens and 1 duck. Well we had a 8ftx12ft shed built for use a few years ago for extra storage from the house. It has been AMAZING and I couldn't be happier with it. So I finally have saved up enough money to buy 1 more! It'll be next to the other, but barn colored I will be selling all my coops and fencing for my runs to help out just a touch more. They will be custom building a chicken door inside of the main door as well. Along with two 2ftx4ft sliding windows on either side. A sun 2ftx4ft light box in the ceiling,two 16inx8in vents on either wall at the tops for ventilation and I will get an 8ft side with a 16ft deep shelf and the back 12ft wall with the same, leave one side without a shelf for storage and such. I plan on placing the roosts above one side and making the shelf a poop board and then nesting boxes on the other. I am too excited. Finally wont look like a mess in the backyard with a million little baby buildings, haha.
