Naw, just a good discussion!
If you can get it for FREE--I say, go ahead, just make sure it doesn't smell a lot (have a lot of aromatic oils, like cedar does). These can bother the chickens' lungs and apparently kidneys.
I use wood chip in my run, and in the coop when I can get really dry, non-smelly, non-moldy stuff. Once the stuff is mixed in with the poo for a while (about twice a year), I dig out a lot and put it directly on my garden. Note, I said directly. I'm a landscaper, and people worry way too much about too much/too little nitrogen/carbon, etc... If you're not tilling it into the soil, and it's not super high in chicken poo (like straight off the poop board) you really don't have much to worry about. I wouldn't throw it on new seedlings, but for established beds, it is just fine. BTW bark makes a super good soil amendment when it breaks down.
