Well, I've been looking over some other threads about duck behavior, but I couldn't find anything that explains what my Ducks are doing! I have a small flock of Khakis and Welsh Harlequins. Every once in a while they sidle up to me and start looking for treats, nibbling my fingers, and nosing my hands. But now some of the drakes do this 'neck thrusting thing' over my hand and up my arm! It's a very quick sharp movement. It doesn't seem aggressive, but I don't know. Anyone have any ideas?
