Can a duck and a rooster live together in harmony? I'm thinking in terms of a companion for a rooster who is living alone right now. No, we cannot give him a hen for a companion. He'd mount her so much that he'd probably injure or even kill her. Roosters need many hens, not a single hen, and we cannot provide that for him. But I got to thinking -- could a duck provide him companionship without being subject to repeated "mounting?" Could a duck live with him in his 8 foot by 3 foot by 2 foot high chicken tractor? We let him out to free range in our back yard during the day, and can do that for the duck as well. But at night they would need to sleep together in the chicken tractor. Also, in the worst of winter when it is too cold and wet for the birds to be let out, we would need to confine the two together in the heated chicken tractor together all day as well as night, maybe even for several days in a row. Could a duck and a mild mannered rooster co-exist like that? And if so, would a male or female duck be a better companion for him?
