I am trying to reinforce my coop before my chicks are big enough to go in it. I am terrified about raccoons getting my babies. What has worked in the past for you all? Should I bury wire around coop? Can I make a wire floor ( attach wire to base of coop) and then just cover it with sand? My neighbors are HORRIBLE about keeping their trash cans contained...hence the raccoons. I have some time to work on this...chicks are only 3 weeks old.
