Hi, I am first time chicken owner with about 5 week old assorted breed pullets in new coop using pine shavings.I keep hearing everyone addressing moisture and ammonia in the coop? I am confused because I am pretty sure from cleaning after horses that ammonia is a result of old urine, and to my knowledge chickens do not urinate, only poop? We have had them moved into coop about 11 days, and at first were warned and worried about the smell.i smell nothing. I use a cat poop scoop and pick up twice a day, turn the shavings over while they are outside. I put about 8 inches of shavings when they moved in. No smell. No moisture. Am I doing things right?
