We are new to raising chickens, and have 6 chicks growing up fast. We are converting an old dog kennel with an attached run. It has a cement base. Looking for suggestions on how to make it chicken friendly. We are planning on adding plants and herbs in containers. Should we make areas for grass or dirt? Or just cover it all up with shavings or other bedding? We are planning on using pine shavings to line the inside of the coop. Should we worry about making it deeper because it sits on cement? Thanks for any help and advice!
