We're moving our chickens into a barn from their current coop. I'm looking for roost ideas. Anyone have pics of roost structures they have built? We'll want ours to hold about 30+ chickens. I've seen the ones with 3 or 4 rungs in a ladder-like design that I really like, but how do you keep the chickens from pooping on each other that way? We've got all sizes of chickens from the tiniest little BTW jap to a huge fat Tyson broiler (that we rescued from the side of the road), so the ladder idea is appealing to me for how far they are able to fly up. TIA!
