Hi, I have ducks and geese that I have raised together. They eat greens, oats, and purina flock raiser. Well on the bag of flock raiser it says to switch them to layena at 16 weeks. The ducks will be laying a lot of eggs, so I seems reasonable for them, but the American biff geese will only lay 40 or so eggs. Is this good food for them in anyone's experience? Has anyone else had a similar issue feeding geese and ducks? I am hoping my trio of geese will breed so I want them to be healthy.
