I have six muscovy ducklings. They are only 3 weeks now. I was told from the person I got them from that they could live on the lake at 4 weeks. I don't believe that is possible. She probobly just wanted me to take them. Boy they have a lot more growing to be out there on their own. The thing I would worry about the most would be hawks. I would put them in their pen at night. Do racoons bother full grown ones if they stayed out on their own. I mean is that a choice or should I always pen them at night no matter what.
