For us it's always been simple. Our coop has NEVER smelled. Not in any season. Not ever. We take a bucket of sudsy warm water out every single morning early and clean it. Everything gets a wipe down; poop tray taken out, scraped into a separate special bucket that we empty in the compost, then washed over the soapy water bucket. This is all not as complicated as it may sound. Coop and the run take maybe 15 min., 20 max. Also, and this is a HUGE help, we have SAND in coop and run. Poop is easily scooped out every morning with a kitty litter scoop with the holes. Sand just runs through. We would never use anything else but clean, construction sand. Chickens also are not walking in poop all the time, etc. It's been almost 5 years now, and we rarely ever have a hen get sick, and the coop and run have never smelled at all. The key is that this is a daily routine we do, regardless of the season. It also prevents any yuk from building up on floor, walls, nest boxes, perch, etc., because they are cleaned daily. Two times a year we take everything out and Clean the coop with that spray Kennel Wash and then the spray disinfectant that prevents any bugs, etc. (Both of these attach to the hose). One thing that also really helps is that we painted the inside of our coop with a scrubbable, semi gloss paint. We highly recommend you don't leave the inside of the coop unpainted, including perch---(we have a wide 2x4 board for them), nest boxes, etc. Hope this helps!Soooo I've spent a while searching around, looking at threads about this, but I want my own one, and more specific help.
Last summer, my coop ALWAYS stunk, I cleaned the roosting boards daily, had deep litter, but coming within 15 feet of the coop, you would be hit in the face with chicken stank and flies.
My coop is 8x8 and currently has 15 chickens, will be 20 soon but that's about my max for this coop. I had about 6 inches of pine shavings, straw, leaves, pine needles, and anything else I could find in there.
I did not use pdz in there, but I have a bag and will start using it soon, I'm hoping this will help as well. I am located at the very top of North Carolina, so summers are hot but not awful compared to other areas.
The coop stays very dry as well.
Based on the info I've given, does anyone have some extra tips for me coming into this new year to keep my coop not as smelly?
