@chic rustler try tomatoes on it the first year... if it is down a foot or two by the time the tomato roots get down that far it's done being hot.
as for chicken processing of things, some designs put the chicken run uphill, pile the stuff for them to process at the top of the run, let them move it downhill for you, by the time it gets to the bottom it's done.
if it is dry and sandy soil add a little clay (it doesn't take much) that will help hold moisture and nutrients in place.
worms love bunny poo. bunny poo is one of the few garden amendments that can be used fresh on gardens and won't burn plants.
i've never seen sheep poo. do they do pellets or plops? does it smell good like horse poo?
@baymule, yes, if you can get free woodchips they are wonderful material if you don't get too much other stuff ground in with them. sometimes the crews will chip plastic containers and that's a pain to pick back out if you don't catch it.
same with bagged leaves. sometimes people rake up the leaves and there's a lot of trash in them and then shred them to get more in a bag. what a mess that can be if you don't know that before you dump the leaves all over. i no longer pick up random bags from along the road because of that. too much work later picking trash out of the gardens. one load a friend brought me had so much trash in it i found a clock, kitchen knife, motorcycle headlight, and all sorts of other things too. what a mess... had a similar problem with compost i brought in once before inspecting it. mistake. still picking plastic/glass/metal out of a garden from that... last summer i did a pretty good redo on that garden so i hope i finally got it all. shredded plastic candy bar wrappers. shredded aluminum cans. bits of glass and plastic. diapers. ick...
@RUNuts i think that kind of environment is similar to their natural habitat where they have stuff to pick through and look for bugs, etc. dogs like anything smelly. it's like some people and stinky cheese.

someone told me they like to roll in dead things because it masks their scent. um, well, no, cuz then you can smell them coming a mile away...
