We have been using pine shavings on the wooden coop floor, but are thinking there may be a better option. I have heard some people use sand, but was curious how that has worked for you. If you have other cost effective ideas that work for you, I am open to those as well. The cost of pine shavings start to add up. I want to make sure I'm not inviting in pests/bugs as well. Thanks in advance for your info!
