I have a barn with different flooring areas and I want to know which area would be best for the ducks. One room has concrete flooring and the other is dirt. Currently I have hay and pine shavings for bedding in both areas. I usually keep the chickens in the concrete one. (I currently have guineas in the other, but they aren't long for this world and I want to try ducks to take their place.) Each of these rooms is 8 feet by 12 feet. (I also have quail in another smaller dirt-floored room, also with hay/pine shaving bedding.) Should I put the ducks in the concrete room or the dirt one? I usually only replace the chicken's bedding once a year, just adding more layers throughout the year. If possible I'd like to do that with the ducks, too. (I know ducks are messier, so I'm not sure if this is possible.) I have a large fenced pasture where they can enjoy the outdoors during the day once they are old enough. One of the reasons the chickens usually are set up in the concrete-floored one is that it has a split door that I can keep the top half open and the bottom half closed. During the day when the chickens are free-ranging in the pasture they can get in to lay eggs and eat, but the other barnyard animals can't get in. So all things being equal I'd rather keep the chickens in that one, but if it would be way better for the ducks to be in there then I can change the arrangement. What do y'all think?
