I use a three bin system, located directly behind my coop.
I fill one bin with kitchen waste, lawn clippings, and coop sweepings(both poop and pine shavings), then allow it 'cook' down for a year while I fill the next one. The following year I harvest while the second bin cooks and I fill the third. You would not believe the rich, dark, worm filled soil I harvest every year.
If you add animal waste like chicken poop, you really should allow it to cook for a year before putting on your garden, just to be safe about bacterial contamination.
Pine shavings from the coop are a great source of Carbon, which is necessary for an active Nitrogen cycle. In fact, the more Carbon you can add, the 'hotter' your compost pile will be, and the quicker it will break down. Keep in mind that pine shavings will increase the acidity of your compost. This is fine for acid loving plants like tomatoes and strawberries.
Pallet compost bins work wonderfully well, mostly because they allow a great deal of air to get into the sides of the bin.
Tumble composters, in my opinion, don't work well because they can't handle a very large volume of compost. Four chickens will produce copious quantities of poop, and combined with pine shavings, you will quickly overwhelm a tumble composter.
And finally, a properly cared for compost bin won't stink. If it ever begins to stink, that is a sign you have the wrong kind of bacteria growing. It's probably too wet, you need to turn it, adding in a shovel full of sawdust or pine shavings periodically.
