This winter my 4 penkin ducks finally found our pond in the backyard and have been going out during the day and back home to their hut at night for me to close them up. Now the weather is getting better and I'm not able to get them back home! I've tried food, treats, and nothings getting them to budge. It's going on day 3 of them living at the pond and I'm worried something will happen to them at night?! Should I keep trying to coax them in with food or just let them be ducks? It seems like yesterday they were just little bundles of yellow fluff!
