We had a great discussion on the forum about composting here. This article is just a reference for me and others with the highlights from that discussion.
Composting chicken poop year round you need a source of carbon to balance out the nitrogen. We all hear about greens(nitrogen) and browns (carbon) but in a nutshell greens have a higher nitrogen content than browns and both have nitrogen and carbon. You need more carbon rich stuff than nitrogen rich.
Stuff with higher nitrogen (greens)
Green Plants (grass, leaves, trimmings)
Vegetable and fruit scraps
Stuff with higher carbon (browns)
I have 3 bins and rotate them, I keep the bin with the fresh poop covered up but let the chickens dig in the other two bins. I add poop and carbon rich items. If you know a wood worker they will have all the carbon you need. If I start a new pile I add nitrogen items like grass clippings along with shredded paper or sawdust and water it down good. Typically you leave your pile alone when it's hot and turn it when it goes cold.
If the pile is gummy and sticky and or smells add more carbon.
Some photos of what I have. This is my finished bin, nice and clean earthy smells, powdery can't hardly pick it up with a pitchfork. Chickens are allowed to dig all they want in the finished pile.
This is my working active pile where I add chicken poop, water and sawdust or leaves and I have to turn this one before I let the hens out or I'll have 5-6 hens in there digging for worms. I did water it after I took this photo... and I don't let the hens in here with fresh poop. When I stop adding poop I'll let it sit for a few months before taking the cover off.
Last but not least is my fresh starting pile. It's a mix of leaves, grass, and kitchen scraps for now. I water it well and let the hens dig in there all they want. When I stop adding poop to the active pile and start adding it here I'll cover it up to keep the hens out.
