So, I think it mainly depends on what plants you are putting it on and what your soil is like already. My soil tends towards acidity, so the chicken manure and pine shavings can make that worse. I usually just let it age a bunch, and then keep that fertilizer off of plants that need a lot of calcium (cabbage mainly), since acidity can affect uptake. You may need to be sure things stay in balance for certain plants, but if you are letting it age for a while it will probably be fine to put on most stuff.
I will also let the shavings/droppings age on fruit trees and berry bushes.
I just read this about zeolite, it helps absorb water and retain nitrogen. I'm not sure if you can overdo it, such as it may be too much nitrogen for fruiting plants like tomatoes, but I'll bet it will come to a balance if you are adding other things to the mix and letting it age.
