I have six khaki campbells and I put all of my time and energy into assuring that they are happy. They have a swimming poop, plenty of grass to graze on and a well bedded house. Though they still freak out as if the world is ending every time I come within five feet of them. I know they're ducks and that it's a natural instinct but it really gets in the way sometimes. For example, if I am inside of their enclosure to refill the water they fly over the fence and escape just to get as far away from me as possible. Then it takes me the next 10 minutes to catch them. Is there anything I can do to gain their trust and make them calm down? Can I train them in any way? Thanks for the help.
