I will be having my duck house, chicken coop, and common area built within the next month and I would love advice on bedding! As of right now, I use hay with my two Call ducks. I want to use the most practical bedding, that will look nice and be easiest to keep clean! Does anybody use pine or has anybody ever used gravel, sand, or bark? Please tell me about your experiences and fill me in on what has worked out the best for your ducks & chickens! Thanks!
