I have been keeping my chickens in a 10'x20' chain link dog run for about 4 years. We have mild winters in central Texas, so they don't really need an enclosed coop. They've gotten along just fine with a tarp over one corner of the run to provide shelter from the elements. I just don't like how it looks, so I'd like to build a 3-sided shed to serve the same purpose. There is a mill near us that processes cedar trees and makes boards with the bark still on the edges. It looks really cool, especially when it ages and turns gray. Since the shed will only be 3-sided, do you think there will be any issues with the cedar smell for the chickens? I'm assuming the open side will provide enough ventilation that it won't cause a problem, but I wanted to get opinions on using the cedar. I don't know if it makes a difference, but this would be local Texas cedar, also called Juniper.
