Hi all, We have about an acre of our property fenced near the house. Inside that acre, we built our ducklings a predator-proof house and little backyard pond, and enclosed both within a low fence. They are absolutely loving it! They're out all day with free choice feed and water, and we close them in the house at night without feed and water to keep it clean. They've been out there for a couple of weeks now, and each night, we chase them down and put them in their house. Here's the problem, though. . . Our future plans for them were to allow them run of a much larger area, if not the full acre itself. But there is NO way we could chase them down over a larger area each night to put them in their house (let alone the full acre!). We do have night time predators, so we'd really like them in each night. Does anyone have any ideas for how to train them to reliably go in each night? Thanks in advance!
