Roosting Bar with Sweet PDZ Horse stall freshener underneath - no dust or smell, & scoop poop out with kitty litter scoop every few days.... also, not a lot to throw into the compost pile except the poop itself. Don't forget to build an edge around the poop shelf hold in the PDZ. Also consider making the shelf accessable from the outside at "wheel barrow" height.
Train your chickens to come when called, so you can let them out and get them in anytime you want. Also enables you to call them to safety when predators lurk. If you have multiple flocks, you can train each to come to a different call. Very helpful when you have new pullets free ranging with old flock, and need to get each flock to its own coop.
