In the process of building "the" coop. Hubby is putting up soffits. It's a lean to style coop. 10 ft. in the front sloping to 8 ft. in the back. Will the soffits be enough protection against outside critters? I was stapling up screening on the inside tonight up high on the 10 ft side and it is really hard to get around those roofing 2x4s and staple that. I figure I need that to keep flies/bees/bugs down. But do I really need to add hardware cloth on the inside of those rafters too?? Thanks in advance!
