My three Ancona ducks live off of Scratch & Peck organic/GMO-free feed, vegetable treats, and free range in the yard. I have managed to accumulate quite a bit of human rolled oats and wonder if this can be added to their regular feed. I will never eat this much myself, so thought it might work as an extender for their feed (which is getting more and more expensive). Also, I have been getting the layer, higher-protein (20%) but now that I have added the drake for the two girls, wonder if I should change this. They have a side dish of oyster shell along with digging all over the yard. They are laying good strong eggs, but seem to be molting now. I adopted them out of terrible conditions just before they started laying. One of the girls has never had good feathers. I thought her feathers would have improved by now, but she still looks so ragged. They are all happy and vigorous.
