Not sure if this is the right spot. All summer long my coop has not smelled at all. As soon as the weather turned cooler I noticed the amonia(sp) Smell realy strong. I cleaned to coop and changed the pine shavings a few weeks ago and it already smells I know that in cooler weather i will get less evaporation, but something isn't right. I have 3 windows, To roof vents(turbines) and a hinged board in the ceiling that opens for extra ventalation. As the temps drop I am going to have to close some of the windows and roof vents and things will get worse. Am I doing something wrong or am I going to have to change the shavings every other week?
