Hi Fellow CO Peeps! I'm a newbie. My girls are 3 weeks old. We want to make the nicest home possible for them when they make their transition to their big girl coop! We have purchased a coop and will be putting it in a big dog that our new home came with. Currently the run has wood chips down but I don't know what kind so I'm assuming I need to take that all out in case it's bad for them?? Or is cedar only suggestion as chicks? Ack... anyways, what do you all use in your runs?? Thank you in advance!!
