Hey Christina here! Started out with a gift of one rooster and a pulley. Enjoyed the sound of my rooster Jacinto every morning and getting my daily egg from Petunia. Unfortunately, a dog got into the coop and took both their lives. I missed the joy and had an empty coop to look at now.
To fix...
If you multiply 2X2 that would equal 4 sq ft. For 13 personally I would think you would only need 26 sq ft for you 13! Your waaaayyyy over in required space.
