My poultry feces and lawn clippings are the basis for my composting. Most of my flock is free range but the free rangers do roost in a coop at night. I use the deep litter method and let most of the feces just mix in and compost away. But from time to time I'll remove large piles and either take to a separate compost pile or drop in a drum filled with water that I keep full of feces and wood ash from my fire pit or smoker. I let that stuff ferment or whatever its doing for weeks then use it as a liquid fertilizer on individual established plants.
As far as composting on mass, I use the bottom of my runs to give me an almost infinite supply of rich dirt for starting seedlings (individual breeding groups and my OEGBs get locked in the runs so they provide a lot of feces enriched dirt pretty quick). As where my OEGBs are coup and run bound, I also take out the tray of their coup sometimes and add to garden compost piles. Its filled with weeks worth of roosting poop mixed with their bedding (pine shavings and bahia hay).
I make large compost piles in the corners of fence lines that's stacked fence-high with bahai clippings from when I mow the lawn (my lawn is near 2 acres) and I let that stuff break down, and its these piles that I'll add big piles of roosting feces to every so often.
My guineas roost on the OEGB coop and sometimes I can collect their feces on the tin roof. But its not efficient to do so.
I can't make enough compost this way to fertilize my several acres of blueberries, but its more than enough to meet my gardening needs.
