We have a 7x15 coop with 9 chicks that are 6 weeks old and one Pullet that is 7 months old. It's a cement floor. The base is pine wood pellets and then there's leaves all over the top. The last two days it has really begun to STINK. I'm really hoping I can fix this. I would like to have a composting coop with deep litter. So I'm wondering what to add next. I got the girls all out of there today and stirred the whole coop up which seemed to help a bit with the stink. I really don't want a stinky coop!
