Hi, I have three mallards, 2 drakes and 1 hen. I had them pinned up in a coop while they where young but for the past 3-4 months I have left the gate open and they havnt been back in it. We loved having them run around the yard, pecking at our feet, and listening to their nonstop quacks and grunts. The only down side was they loved our porch and have pooped all over it. About a month ago the hen found her way to a cow pond behind the house and hasnt returned to the yard. I have a baby on the way and its time to put a stop to the poopy porch. I took one drake to the pond with the hen. Once he saw the hen he followed her to the water and seemed to forget all about the house. I took the other one to another pond on the other side of the house. He spotted the house and ran to the fence and is still standing there right now wanting into the yard. My question is, if I take the loner drake to the pond with the other ducks, will the drakes harm the hen once they start breeding? I have heard that if you have more drakes then hens then the hens could die from over breeding and I dont want this to happen. Any info would help.
