I am planning on a chicken coop of 10 X10 foot design. The run is going to be about 10 X 30 feet of wire (covered with wire). The Breed that I am hoping to raise is what I used to have many years ago. The would be Barred Rock. They are a good hardy breed and are good layers and also meat chicken. I really believe that the day is coming soon that we are going to have to be self sufficient as much as possible with what we are seeing with our failing economy and so on. My question is how many hens do you think that I can keep in this size coop and run? Any response will be greatly appreciated.
