have 3 female pekin ducks. They have the run of my suburban yard and I buy them organic poultry feed. In the winters here they are eating the poultry feed 95% of the time. They don't seem to eat much table scraps before it freezes. I keep the feed outside of their house because they dump it a lot. I have read that ducks need the addition of nutritional yeast to the feed because it is formulated for chickens. Is this true? I have been adding a sprinkle on top but I don't know how much is needed, if any.
The ground is still frozen here and I have been giving them thawed out frozen peas as a treat. Will this throw off their clock for egg laying? I don't want tem laying too early because they hide the eggs and I find them frozen.
Also, one duck has a much lighter colored bill than the other 2, even when they are not laying. is this normal or is she lacking in some nutrient or vitamin?
