Hi! We are about to transition our chicks out to their new coop. I am really struggling with what I want to do for bedding/litter. Our coop sits above the run and is about 5'x5. To access the run (always open) there is a large opening with a ramp in the middle of the coop floor. I want to put something down but don't want all of my litter falling into the run on a daily basis. I need some suggestions. Am I thinking too much about this? Ideally I'd like to use sand so that I can scoop out droppings with a mesh-like shovel but I'm also really worried that will just be too messy with the ramp access in my coop floor. I don't imagine straw would be any cleaner. Help! Pic of my half finished coop!
