I split my coop in half for the chickens and ducks to separated.....too much wetness! They will share an outdoor run that I have almost completed, just need to hang the net. The sawdust that I am using for the coops is getting really gross on the duck side. They splash water everywhere and there is always a huge wet mess under the waterer. Is there a better bedding to put in there that will be better for them and easier to clean? I tried to make them a bed area with straw and by morning it was strewn all over the place. Should I make a box on the floor to contain the straw?
