I have this chicken hutch....or coop...or whatever it may be. It is in my yard, sitting on grass. I have three chickens (who I got today) and they have eaten a lot (almost all) of the grass in the underside in less than 12 hours! I figured, I would let them finish eating it until it is all dirt underneath....but then what? Do I leave it as dirt underneath or do I add shavings or??? I am totally confused as to exactly what the underneath is supposed to be like. It's weird, I thought I knew what I was getting into and now the simplest things are stumping me! Please forgive my ignorance! Here is a pic of my little chicken "house." Any suggestions?
