This is the indoor run my husband built me inside what long ago was my Great Grandfather's Guideboat workshop. I wanted to have a place for the peeps to go in the winter so they wouldn't be cooped up inside the coop when the weather is bad. The coop itself is at the end through that door. It had been a bathroom years ago, we tore out the floor and walls and re did them and added another window. Hubby took out the panels and covered the holes with hardware cloth for ventilation. I want to put 2-3 smaller pens on the other side for emergencies, broody hens, breeding etc.
