Hi all, first time duck mom. I have 2 ducks and 4 chickens, all about 3 months old. They usually tuck themselves in at dusk and all go into their house, but for the past week, one of my ducks refuses to go in! He just stands in the run shouting, until I finally give in and go put him up. I've tried guiding him into his house, but he completely stopped doing it by himself! I would let him stay out if he didn't shout the whole time, but he wants to be with the other birds... I think maybe he wants them to all stay outside with him? Any thoughts or ways to fix?
