That's very interesting! My ducks must have unusually bad night vision. I feel like I have better night/dusk vision than they do. When I give my ducks mealworms at dusk I have to put my hand right under their bills. Until they feel my hand touch their bill they behave like they don't even know something is happening and just stand there. Then they feel my hand and gobble! During the day they almost attack and trample me for mealworms! My ducks also go inside the barn at dusk and refuse to come out until morning, I hear other ducks like to stay outside at night. Maybe my ducks want to be inside for a reason?
But, my ducks are older, 6.5 and 7.5. And I'm curious about the domestic vs wild as well.
