I'm planning on building a 10' x 10' x 6' run for 6 chickens, an Easter Egger, a Black Astralope, a Buff Orpington, a Gold Laced Wyandotte, a light Brahma and a Welsummer. I'll have a 4' x 6' raised coop inside. I'm using 1/2 inch hardware cloth on the sides. A couple of questions, would it be OK to use 2"x4" fencing for the roof of the run to keep out hawks and other predators? How tall does the coop need to be inside? I want the bottom of the coop to be about waist high for ease of cleaning. BTY I did find a good use for chicken wire. I'm useing it to cover the cat run.
