I've been reading some great posts and found the answer to one of my biggest worries, how to keep the coop from getting dingy inside and that is to put lino down on the floor so you can wipe clean! Genious! Does anyone have their run on concrete and if so would you recommend putting lino down in the run too before putting the sand ect on top?? I'm just thinking it will be easy to use a pet safe cleaner again on the floor once I've raked up all the sand. Thanks!
