Is it wise to use fresh wood chips? Thought I read that they needed to "age" before using them in a coop/run.
I saw that too, so I was wondering about that. Unless they maybe have a store of them that have been sitting around. I live in a really small town without access to alot of things, unfortunately.
Best to NOT use fresh chips. Ideally you want to age them out a bit... 3 months, 6 months, how much ever you can wait.
Call some local tree service companies and ask what it'll cost for them to drop a load of chips off. In my area many companies will do it completely free. Obviously you will need space to store them, as they can drop several cubic yards at a time.
Do not expect for the tree service company to age them for you. THey will likely arrive with the freshest possible chips, chipped and brought straight over from the last assignment they were at.
