Gene Logsdon in his book "Holy Shit", seemed to think that putting dog shit in the land-fill should be a crime.
As William said, Jenkins' most recent Humanure Handbook is a good reference for getting it right also.
My key take-aways were to have lots of absorbing bedding under and around the pile of shit. The chicken shit can really heat up. Some parasites can survive decent heat and have protective coatings, but if you let it sit a couple of years and then use it around
trees, preferably covered with fresh mulch, I suspect your healthy microbes will take care of it.
Not mentioned by Gene or Joe, but from more recent reading, adding charged
biochar to the mix can do really good things also, and it's not that hard to make in small quantities (we use an old stainless pot in our
wood stove in the winter.)
