Hi, I have 6 Muscovy ducks and 1 goose. They have a pond, and I have 2 houses that I can close at night for them. The ducks like to roost most nights or else stay in the shallow water, but we are hearing of coyotes and such in the area-and I really want to make it routine that they all go up at night. Do you guys think some special treat would be the most likely way to bribe them into their house? They are tame, but just will not quite let me catch them. Any special treats that Muscovies and a goose would not be able to resist? They snub their noses at cat food and lettuce. Meal worms are next.
