I'm getting ready to order my new group of chicks and want to make sure I don't make any mistakes. Can I use Aspen shavings (they are a lot cheaper than pine) for litter? Any special thoughts? I raised some two years ago, and by some trial and error on my part got only half of them to get to maturity. Learned a lot about predators, especially racoons. Now my cages have much smaller mesh. I love the chickens I do have, but now that they are older, they don't produce but maybe one or two eggs a day.
