We have pretty good size pond, about an acre and a half and have been trying to keep ducks and geese on it. We always lose the ones sitting on nests.Our pond connects to a creek that's very wooded and swampy and impossible to search for nests.We have one goose and one duck left and 3 wild Canada geese that adopted us a few years back on our pond now and I would love to try again but don't want anymore deaths. How do y'all with larger areas keep your foul safe. Do you build houses for them, lock them up at night? Snakes are a big issue and the thought of them getting in the houses scares me. We kill water moccasons every year and honestly I wouldn't go near a house near the pond with a 10 foot pole. I don't think mine would go into anything. We did try making a raft for them and putting it in the middle for them to nest one but they would have nothing to do with it and its sat empty for years.
