Look out for the yellow one!
Update: Sorry for the random video - I enabled cross-posting from blip.tv (when not uploading direct from their website) and forgot all about it. I was trying out UpperBlip the Mac client to upload direct from your desktop.
The video is of some ducks at work - a mother with her 10 ducklings (with one solitary yellow one). Quack Quack!
They stick to mommy no matter what!
Adorable
