Manure generates a lot of heat as it decomposes. Not advisable to store it in large piles. Once it ignites it can be very difficult to put out. Not to mention the stink that can travel for miles under the right conditions and seriously aggravate your neighbors. Not advisable to try to burn with accelerants either, manure has a large nitrogen content, remember the Oklahoma City bombing.

There are several ways, I know of, to get rid of it:

Ask around your community, post a free flier

I found one neighbor who hauls it away, by the truck load, to use as land fill and in his garden, great tomatoes,.

A soil enrichment company a little ways away processes it and mixes it with screened dirt to resell and compost dirt.

I spread it in to paddocks with my spreader and re-seed twice a year.

Some people get lucky and live close enough to places that pay you for it.

Once it's spread out and broken up it takes no time at all to break down. I also have a small deposit of it that I constantly turn and mix to make my own "horse dirt".
There are many products on the market that will help break it down faster as well as provide fly management.

Keep it away from the barns. If you get one fly, and don't use any precautions for fly control, in no time at all there will be hundreds and thousands all over the place, in your face, on your animals, in their food, and leaving behind those annoying little puke dots all over the place that are a pain in the but to clean off. Yes for those who didn't know what those little black and brownish, pin head sized, dots all over the place were. It's fly vomit. That's how they digest their food. Just like a cow they eat it quickly, fly off to safety, and vomit it back up to break it down further, then re-consume it. GROSS. Start fly control as soon as possible..
