We moved into a 220 yr old house with a bunch of outbuildings around it. One of the buildings has three rooms with separate entrances and I chose one to be the chicken house. It has an antique glass door for light, a window, and a peaked ceiling. There is an ancient armoire that the floor was actually built around, so I removed the doors and will be using the shelves for nesting. I hung a feeder and waterer from the rafters. I nailed boards over wall and floor holes, sealed up openings with small gauge wire mesh and am really excited to finish it up. My first problem. Ventilation. I was given two vents that have the little sliding lever. Are these appropriate and safe for a chicken house? I need to get up into the rafters and cut a hole to install them. Do I need to do that or is there an easier way to ventilate? Second. I decided to rip the woodshed lean-to off the back of the building and make a wrap around run. This would give me a run across the front of the building and around the side. The reason for this is to allow the girls a place to roost in the shade if they wish. I have noticed some posts from people about what to lay down in a run. I was going to get pine shaving for the house and then let the run be grass... am I mistaken? Any tips or pointers will be appreciated.
