Our coop is new as of October and we've had chickens out there since the beginning of November. We have 8 hens. The coop is 32sqft and 8 feet high. It has a window that is 6ftX2ft on the one side and then another vent above the door. It is SO damp this time of year in BC - it's hard for anything to dry out. We've been using shavings, and a few flakes of straw, as well as dry leaves as they blow up in to the greenhouse. The litter is about 12in when I fluff it up and turn it. I've been turning it every few days. Today I noticed a very strong smell of ammonia when I turned it, so I opened the door for awhile to air it out. I think it's near impossible for it to be dry, when we have 6 months of rain! Any ideas? Should I take out half the litter and throw another bale of fresh shavings in?
