We have had difficulty with predators lately, and recently lost a beloved chicken to a horrible massacre. We are keeping everyone indoors at night while we secure the coops. They are already built and have poultry fencing, but we are adding 1/2 inch construction mesh. My question is, what to do about the floors? Currently they are dirt floors with straw. We are pulling out all the straw to insure that we have all the gaps covered, and to secure the floor. Do we cement it, wire mesh it, a combo... Bury wire outside the coop.... We do not want anymore deaths or injuries and do not want to end up trapping our birds in with a predator, which is basically what the previous wire did.
