I initially felt like that until I found the story about how Wrinkle came to be alone. The couple -- there is a female partner for the guy in the video, she is presumable the videographer -- wanted ducks and sadly only one egg, the one with Wrinkle in, hatched. They did their best for an unexpected lone duckling. I have a rescue that came to me at 2 or 3 days old on the verge of death. I nursed him back to life but then he "collapsed" 3 days later, lying in the corner on his soft toy and not eating and drinking. I recognized a depressed duck and then kept him close by me with lots of handling [he wasn't interested in mirrors except to look at me and make sure I was still there behind him] and he thrived. He is now 2 years old and a great lump of ducky affection. He's not a house duck like Wrinkle as I was able to get two more rescues when all three were about 8 weeks old from a rehabber. My duck is deeply bonded with me but came too late to imprint on me [fortunately].
Wrinkle's human Dad and Mom weren't in a position to find more ducklings from a rehabber, and really have done the best for Wrinkle including 24/7 attention. I suppose Wrinkle's human Mom is camera shy as she was in some shots in earlier videos.
It is the Wrinkle story that lends me to advise people not to have a single duck as a house pet: adolescents with a single house duck who go to school and leave the duck alone during the day are really being unkind to their duck. Unless a person can devote 24/7 attention like Wrinkle's humans, and take them out into the fresh air and sunshine every day, ducks shouldn't be alone and shouldn't be house pets.
So I am nolonger sad for Wrinkle, but am sad for most lone house duck pets.
