Can anyone provide an alternative to having wood as the interior of the coop/night time house? I am somewhat holding up my husbands progress on construction because I don't care to use wood due to the issues with mites, as well as wood not drying well when washed out...has anyone ever used hardy board or shower board, or plastic material and nailing/screwing it over the top of wood for easier cleaning and durability? We are somewhat newbies, any info provided will be helpful! Thank you.
