I started my flock in April. I now have two coops. One has 12 layers and the main coop has 28 layers. The large coop is an old shed that we transformed into a coop. It works well. Still need to add winter lighting and heat but other than that it works well. I'm trying the deep litter method and I've noticed that the worst place in around their roost. I've cleaned that area up and I've been using Lime dust and adding a layer of wood shavings. Still it smells after only a couple of weeks of the new layers. I'm planning on cleaning it down to the dirt in a couple of weeks and starting over. So it lasted about six months. Does anyone else have any success with the DLM?
