Hello McIver,
Sounds like lovely weather over in Kellogg, too! I'm out by Callender -- near Fort Dodge.
What kind are your remaining ducks? My Indian runners are so food motivated that I can get them to follow me anywhere if they even hear me open the metal garbage can where I keep their feed. Also, they love grapes -- which I toss out as treats. They gladly trot into their night shelter when I yell, "House, house" because they know dinner awaits.
Having said that, I can't say I have ever cuddled any of them or watched TV with them (I'm jealous!). Most of mine were hand-raised by me, and they STILL don't want me to hold them. A couple of my older girls will allow me to pet them, but I only get to pick them up if someone traps himself or herself -- or if someone is injured.
One problem with ducks is that they have a higher tolerance for cold than most chickens (who thoughtfully put themselves to bed at my house -- most days). Do your ducks have a pool? Mine can't wait to get out of the shelter -- even on the coldest days -- to jump in their heated water dish to bathe. Can you lure them into the garage with the promise of bathing water?
Good luck with your contrary birds.
