I think I know what I want to do with my coop, but not about the run. I'm new to chickens, so please don't think I'm stupid, I'm just ignorant. I want to put them in a run that is about 60x60, not measured it. It's actually a dog pen, but he's gone now since this morning.. But now I have a run . It's going to be very expensive to cover though!. What is the cheapest way to cover it. My babies are about 14 weeks and perfect hawk snack!!! I've seen about 4 of them this week and when my chicks were free ranging with me watching 3 came out of the woods and flew around. I never knew I could gather that fast! Anyway, I don't know what I should use to cover it.
