The droppings tray usually located under roosting poles, because that's where most of the mess occurs (your flock remains on the roosts for long periods at night). In smaller coops, it may make up the entire floor! Again, just pull out your droppings tray, then turn out the contents into your compost bin or pile, add fresh bedding, and put it back in place. Easy peasy! And remember: the cleaner the coop, the healthier your flock will be.
