Just to be sure, I wouldn't advocate not having a top on anything. On a daytime run it's OK, but all my chickens sleep inside a fortress coop. Otherwise I'd have zero chickens left. It's just that I can easily see anything trying to get in during the day and zero them in on my scope...what fun! During the day a cargo net and tarp are just a baffle to hide chicks from sight...these hawks are too wild to hop around the coop. We have few coons left in this area..dogs mostly, coons hunters for the rest. Right now a bobcat is terrorizing me and my neighbors...and the resident rabbit population., and grouse, and chipmunks, and everything else. :<
