I have two compost piles of chicken poop. The first pile has a lot of chips within the poop. It's all nicely decomposing and turning into dirt. The chicken poo is all washed down to the bottom or the ground. My husband turns it over a couple times a year. We've used a bit in the garden this year and planting our trees. I was able to plant two little maples myself using the compost pile. I put the compost where I dug a hole since our land is very sandy. Both trees made it.
My husband put a fresh 50lb bag of poop right on a freshly planted 15ft weeping willow this past spring. I had no idea that wasn't the right thing to do, but this tree has already grown a few feet taller! It rained a bit and we washed in the poop before summer arrived. It was also mixed with pine chips, which stayed on the top as the poo washed down.
I'd give it a few months before using. If it rains or you water it down, it breaks down faster. We have both our piles along the woods edge next to our garden. Our first pile I can walk on, there is no more poo on top. I throw weeds and rotten vegetables in the compost as well.
With the new compost, I'll have egg shells, watermelon/apple/pear peelings and of course weeds and rotten veggies. Some people also use newspaper, which I might try.
My hens have all found the big/old compost pile. They make their way daily and eat the bugs/worms that are near the surface. It's a really big pile. I guess they are helping my husband turn it by scratching.
