Ok- my chicks are not quite ready for the big kid coop--but they will be in about another 3 weeks. What does everyone use? I am leaning towards sand in the coop but what's your experience? My plan is to have a ladder style roost with a rubbermaid (flat, under bed style) tub under the roosting ladder to catch droppings to make it a bit easier to clean. would you do pine shavings in the coop and sand in the tub under the roost- so I can sift it like kitty litter-- or sand in the entire coop, or what? Thoughts please! For the run- I feel like I just want to leave it like it is- plain old grass/dirt.
