I have a duck and a drake who free range in my backyard. They have everything they need to be happy and healthy. In spite of all this they will sit by my back door and just hover there. They are destroying my patio and the dogs track in their poop since they sit there all day. So my question to you is how do I get them to go hang out in the yard. I have tons of grass, a garden they pick through, a pond with a waterfall and their coop. It is about a 1/10 of an acre so not huge but big enough for only 2. Thanks in advance.
