Is it okay for chickens little feet to use chicken wire laid directly onto the ground in their RUN and then covered with a hay/sand mixture for the actual flooring? I'm obviously worried about critters come from the under the floor, but didn't want to potentially harm my birds. Inside my coop, outside of putting hay in the nesting box are you supposed to lay pine bedding or the like down inside? After my boys got my coop together the only area is the roosts and the poop pan...do I put bedding down on the poop pan? That seems crazy to me!
