I don't have chickens anymore but when I did, the pine shavings (I used the bails sold at the feed store for horse paddocks) and coop litter went into the compost pile with kitchen scraps, egg shells, grass clippings...
I had two compost piles and added to one for a year then added to the other the following year. The pile I wasn't adding to sat and decomposed for a year. Both piles were turned and watered. The shavings toned down the chicken droppings enough so I didn't burn down my compost pile.
You can't use un-aged chicken residue on your garden - it takes a year to mellow and that gives the pine shavings the chance to decompose.
At the end of each year, I had the most fantastic soil you have ever seen. But it was a 2 year process to get it to that point.
