Alright I need your suggestions! I'm new to owning ducks and I'm about to build their run and house. I have a concrete pad I'd really like to use since we have raccoons, coyotes, and don't want to worry about them digging. I'm planning on building my house out of pallets and leaving gaps near the top for vents and putting hardware cloth over the gaps. I'm planning on putting vinyl flooring inside the house along with straw and painting with exterior paint. I'll be using hardware cloth to build the run and either a steel roof or hardware cloth.. Now this is where I'm not sure what I want to do... for the run I was thinking sand cause I like the idea of how I can just sift it and it's soak up the water, pea gravel because I could just rinse it off and the water would run off the concrete, or what if I did a wood deck so I could cut out a spot for their pool, or get those rubber mats and put them on the concrete so they'd be a easy rinse? I'm planning on letting the ducks out with me everyday while I garden so they get the dirt/bug experience and enjoy the grass... I have two ducklings now and thinking of ordering two more from Metzers while they're still young? What's everyone's thoughts? I live in a location that has 100 degree summers and 35 degree winters... New to all this and don't know what the best route is! Thanks!
