I'm having issues for the first time here. Days and days of rain have made the place a mucky, gross mess. I've changed shavings three times, scoop poop every morning and use DE. Still, I again have an ammonia smell in the coop, which is entirely due to the humidity (well, plus a few more birds in the main coop than should be). All vents and windows are open and I have a small fan blowing air OUT all day long. Still isn't what I like. And Sweet PDZ didn't touch it, either. Rain, rain, go away! And I dont care if we need it, either.
