Just thought I'd do a little intro. I'm Denny, new to raising ducks. We were given the ducklings at about three weeks old (top pic). So we kept them safe in a garden wagon with a chicken wire cover. They grew like weeds so built them a coop & run (mid pic). Like Koa, put them in a bigger environment they grow to match it. At seven weeks (bot pic) ducks and keeper seem to be doing fine. We do live in the city of De Pere, Wisconsin, just south of Green Bay. So two ducks are plenty, city allows four without permit. They never really thought much of the coop, at night just put them in the run where they would stay all night. We started out keeping them in the run at night and while we were at work. Then when they were a little bigger left them out all night. After a couple nights decided to just let them free range in the backyard day and night. We keep the door open and I have seen them go in for a couple minutes then turn around and come back out. We have a small koa pond in the backyard they love. That's where they spend all their time. If not in the pond just chillin' along side of it. I guess that's enough for now. Would like to hear from other cold weather duck owners on what they do with the ducks in winter. The couple we got these two from keep theirs in the garage but we just don't have the room. I did install a light socket in the coop for a 75-100 watt bulb. Finally, I read either on this forum or another forum that someone installed a dog door on the coop. I did and for now just keep the flap up. Just in case they want to go in. Has anyone else used a doggy door? Did you have to "train" the ducks to push the flap to get in? Thanks and looking forward to learning from other duck people.
