Quote: I have open coops, wire on a wood frame with a tin roof. I have sand on the coop floor, very easy to clean. If things get wet I will throw down hay for a couple of days and then remove it to let everything get dry again. It rains a lot here. For my climate I think this is a healthy environment. I don't have very many cold days and rarely a freezing day. If things get bad I take shower curtain hooks and hang tarps all around, easy to put up and easy to remove. Without any forethought the coop walls are just the right size for those cheap blue tarps. Don't you just love it when something works perfect and you didn't plan it at all. My chickens run for shelter in a heavy downpour but don't mind a light rain..... I think they find better bugs in the rain.
