My chicken poop sits for about 6 months or longer. I only have to clean about twice a year under the roost because of my coop set up. Then all poop goes into the compost bed where it sits for at least a month, sometimes several before I use it.
One thing I will caution you about is making sure you don't have nitrogen heavy mixes. I grew sweet potatoes that were BEAUTIFUL this past summer...unfortunately, only the vines were beautiful because I had too much nitrogen which produces wonderful foliage, but not so much fruit. If I had been grown a leaf crop everything would have been great.
So, use your chicken poop, but also use plenty of brown ingredients like leaves, hay or DRIED grass clippings. Green clippings can be used too, but again, nitrogen.
