I have acquired 4 new ducks a male and female mallard and a female and male Pekin. They free range all day eating, bugs, grass, anything they want but they do not touch my feed from the store its purina crumbles. I have had them for a week and they only have taken some cracked corn from me. They appear to be fine, but I am wondering if they are finding enough food. There old owner had a trout stream they basically lived by so I am wondering if they consumed fish? Or even alage? We only have 2 smaller ponds. What are your ducks eating most of? If I have to get fish or some pond plants I will.
