I have 6 ducks and they were traumatized after Aflac died. They dont really care anymore but they runaway/not eat out of my hand. The closest they'll get to me is when I feed them and they eat out of the bowl. Only for a few seconds. My 2 oldests ducks 2yr old Rouen and 2-4yr old khaki campbell will only eat out of my hand if i hold it very far away from me and its a tomatoe. help?
