not sure what to do, I have 3 chickens all different types. Different personalities and not one will quit pooping where she sleeps. I have a hen house I got a murdochs for two hens when the were little. Now they are in a shed (coup) with Hen house inside it, heat, red light, and straw. Two Lay in the hen house, nasty the other has begun to lay on the bale of straw that is Unbundled. They have straw on the floor, I clean everyday. They go outside when not freezing. I have to keep them healthy despite themselves. They won't go near a nesting box, except to walk through it. Where did I go wrong?
