hi everyone! I am getting a Muscovy duck or two tomorrow. My question is, how much water or how big of a pool of water should I have for one or two ducks? Also, how often does the water need to be changed? My husband is concerned that we will be dumping a large amount of water around our chicken pen every single day and that it will keep the ground wet and possibly make the chickens sick. can some of you share with me how you have your ducks set up with your chickens? As well as how you have yourmake shift pond set up for your ducks. Thanks in advance!
