Hi everyone I am new to this whole chicken thing, and as of yet we don't have any chickens We are converting a shed/studio into a henhouse. My husband's concern is the smell the chickens will produce and if it will permanently affect the interior walls which are drywalled and painted. I have seen some pictures of others coops and one used some bathroom wall board on their walls which are easy to clean. I have read of something called Glasbord. Does anyone have experience with this type of shed/coop? Should we be covering the walls in something or will they be fine if left as they are (painted drywall). Thanks for your input/advice!
