For coop I put linoleum down, didn't bother gluing it, use pine shavings with a 3:1 shredded junk mail ratio roughly. Use a plastic lawn rake and throw pieces of bread once a week for the hens to keep it from getting matted down. Cleaning out with plastic rake/broom is simple
cheap, easy to clean, lasts a long time, happy hens, happy owner
my experience is you can find cheap vinyl at big box stores for nearly nothing, ask them if they have any large scraps etc. I did get the thicker kind cause I knew I'd be walking/raking over it
