The conditions (temperature; ingredients, including “greens” and “browns”; size; moisture content; etc.) of everyone’s compost pile are even slightly different, so it is impossible to give an absolute answer to how long it takes any manure to be aged, or ready to use. Under optimal conditions, 45 to 60 days may be adequate for chicken poop, but even that is quite a spread of time in any growing season. However, it is a benchmark. You could try a portion after that period on a one plant or a small area of your garden and see how your plants react. And/or you could have two or three compost piles, with ingredients aging over different periods of time. And/or you could adjust your ingredients and observe the outcome on one or all of your piles. Perhaps the only sure thing to consider is that longer aging, in general, is better ... Good luck! Let us know how it goes.
