Hi! Just a question about a behaviour I've noticed in my female duckies. Not sure if it's anything to be concerned about, I'm mostly just curious. I've got a mixed flock (pekin, saxony, campbell and welsh harlequin) and I've noticed that the girls frequently make a clicking type sound and twitch their head to one side, on a downward angle. At first it was just the khakis, but now most of them have started doing it. I thought they were just looking for food but somehow that doesn't seem right anymore. Any ideas?
