They seem quite tame because eachtime they come, I feed them and the female will even eat out of my hand. The need for large quantities of high protein food may be one reason that male ducks and unsuccessful nesting hens leave the breeding grounds for special molting grounds far away, thereby reducing competition for limited protein resources.
