I compost all my chicken poo and when it comes time to till the garden, all that compost gets added and churned into the soil.Something else I use is Bat poop. I have a bat box and a large bowl that hangs under the bats and collects their poop. Bat poop is very very hot so it can't be used directly on growing plants. I mix about a cupful into both sides of the composter and let it cook with every thing else, for about a month.
Good luck
