He will be a year old this Friday. When do male ducks start to show their testosterone? haha! What signs should I look for? I don't know how I would fence them off in the coop and still allow for the hens to come out to eat and drink. My husband plans on making a separate area and coop for him and his lady friends, but that won't be happening for at least a month or two. He follows her around everywhere. I haven't seen him try to mate with her, but what should I be on the look out for? I don't want to move him out of that run until I have his lady friends. Maybe I will call the lady at the farm today and find out if I can get him a new lady by the weekend. But will the new duck have to be separated from the flock until they adjust? I know with my chickens I have to do that. thank you everyone!
