Our children's fort was sitting in the yard doing nothing as our kids were in college, so we turned it into a coop. We bought Chicken coops for Dummies and figured out what we wanted, taking pieces from many of the different designs. We put hardware cloth around the bottom run adding roosting bars and steps to the door. We added a roosting area to sleep and three nesting boxes. That was the first design, but as we added more chickens, we needed more room. So we added another area with a shelf that can be enclosed for broody chickens, baby chicks and new chickens. When it's not being used, it can be raised up and used as more area for the chickens to move around. The shelf adds shade as well. All in all, we love it.
