Agreed! Not only are wood chips great for keeping the run dry, but the compost is worth every bit of time and effort put into them! I wish I still had my chipper, but it's ability to break down finally outstripped our ability to repair it, {{ ... sigh ... }}My father got a bad case poison ivy many years ago when he was clearing out some wild brushes and trees on my property. It was really bad. The next year he got some kind of a shot so he would not be so sensitive to poison ivy, and he never got a rash that year. Even though I'm not all that sensitive to poison ivy, I always wear work gloves when clearing brush. I also wear gloves when working with wood chips, at home, and at the landfill.
I think the chances of getting poison ivy mixed in with the wood chips is minimal, but if you have someone in the family that is super sensitive, then, yeah, take a pass on free wood chips that you don't know where they came from.
I bought a small electric Sun Joe wood chipper for yard cleanup at home. So I know what is in those chips. Those electric wood chippers do a pretty good job for smaller branches up to about 1 1/2 inches that might fall down from your trees in the yard. Better to chip them up and reuse them with the chickens than to burn them or haul them out to the landfill. It does not make sense to chip wood at home if you consider your time and effort. If you value your time at all, it would be better just to buy bagged wood chips at the big box stores. However, I just put on a pair of my work headphones, load up an audiobook, and chip up the branches with my electric wood chipper while listening to my audiobooks.
If I have lots of branches, and up to 3 inches in diameter, then I get out my gas chipper and get to work. It's a pain to get running, but after that it chips up the wood much faster than my small electric chipper. However, gas chippers are much more expensive than the electric chippers and still they are not very fast. Again, you would be money ahead just to buy bagged wood chips at the store.
But, in keeping with the original intent of this thread, all those wood chips I make at home go right back into the dry deep litter in the coop or into the chicken run to help it from getting muddy. I still think wood chips are the best base to build up the chicken run to prevent it from getting all muddy. Eventually they break down into compost you can reuse the compost in the garden.
