To remind everyone; I am new to the world of chickens and only have had them for a couple of months now. In the past week, their run has been smelling bad as well as their coop. We have been having a lot of rain lately and the heat/ humidity has been unbearable (I live in the deep south!). Could this be contributing to the odor? The flies are even starting to get bad. I have pine wood shavings in the coop, and that smells too. This weekend I am planning on raking that out and replacing it. What else can I do to keep the odor down as well as the flies?
