The coop in question is the one on the right w/ the red roof. Yes, it's small. But it worked for the three hens. I'm in California and our winters are very mild so they only went in to sleep and lay eggs. It has three nest boxes and a 3' long roost. And I would go out every morning and use a kitty litter scoop to pull out the larger droppings. So the coop was basically cleaned EVERY day. I did try the deep litter method twice but could only get to about a month before I just couldn't stand it in there. It didn't smell. But there was just too much in the way of droppings for it to really get started composting. I've since upgraded them to the larger 4' by 4' on the left and now use a poop hammock. I can easily dump the contents into the compost bin ever few days and the coop stays clean. I'm just really upset that someone told me I wasn't doing the deep litter method right and that you could do it in ANY coop large or small. And that I didn't have enough ventilation on my coop for my chickens. There's a big vent the length of the coop along the back and the pop door stays open at all times. (Coop sits inside a predator proof run so they are protected that way.) If I add any more ventilation, they'd be sitting in the breeze at night. So I wanted to reach out to a more knowledgeable group of people and ask if you honestly thought that you could deep litter method in that 3' by 3' coop and only clean it out twice a year?
