This is my Coop and Run. The run is about 8 ft x 2.5 ft & 2.5 ft high. Is this okay for 2 chickens? As you can see in the picture the roof to the run is not on completely yet. I do plan on adding corrugated plastic roofing on top of the run, along with 2x4s on the outside of the run for structural support. & I also plan on adding plywood to all 3 sides of the bottom of the coop so the chicks can't get out from there either.
