We noticed today that the ducks & geese haven't been cleaning up all their feed like usual. This is surprising, since its been so cold here (below 0 at night). Our high today was 2F! I have 16 ducks (runners & harlequins) plus 2 geese. We have 2 feeders set up that get 3-4 cups (as in measuring cup) of feed (Blue Seal pellets, don't remember which) twice a day. They have a heated waterer that we keep full, so they have good drinking water at feeding. I'd think, with it being so cold, that they'd be ravenous (like the alpacas). Is this normal for waterfowl? Otherwise, they're behaving normally.
