We have a single and hubs says no more. She seems content but I have read ducks really shouldn't be by themselves. We are with her a lot but obviously not all he time. At night she sleeps in the laundry room. She doesn't make noise. She knows it's bed time and just lays down to go to sleep. During the day she either swims in her pool or goes in the house. If we are outside , she roams the yard with us. Has anyone successfully raised a single?
