That sounds lovey, but I would highly recommend speaking to farmers in your area @NHMountainMan and heed their advice. If you google “chicken poo” as fertilizer you can see what the percentages are. Do your homework before committing to a plan. Just MHO.If wood shavings have too little nitrogen, that's no reason to shovel off chicken manure that may have too much!
Just till it in, and plant a few weeks later--it breaks down really fast after being chopped by a rototiller and mixed into the dirt.
My Mom (in Alaska, thus cold soil) would clean the chicken house and till it in, and plant fairly soon. certainly within a month. We planted into soil with visible bits of leaves, newspaper, and whatever else had been used for bedding. Everything grew nicely, and by the time we pulled the carrots and dug the potatoes we could no longer see anything but "dirt" because it had all broken down.
My Mom also told a story about the year her Dad cleaned the chicken house, tilled it into the garden, and planted everything that very day. Nothing grew, not even the weeds. So a few weeks later he tilled it again and re-planted everything, and it all grew beautifully. (He was in Washington State, and I don't remember hearing how many weeks was a "few." Probably the time at which all the seeds "should" have sprouted.)
So planting the same day is not good if you've just put in fresh chicken manure, but it only needs a few weeks (month, max) after being tilled into the soil.
If you like to do experiments--just dump all manure from now on, into one half of the garden for this year. Then till it in and plant both halves, and see how it goes.
