hi, just working on our new coop, new to chickens and are using OSB flooring. We live in michigan and was wondering if it is advisable to use vinyl flooring on top or is it better to just leave the wood. People are scaring us saying that that type of floor is going to mold and get really smelly. Any ideas or thoughts would be highly appreciated. also how often should the flooring be washed or cleaned? any help for us newbies would be HIGHLY appreciated.
