There is a feed store a couple miles from the house. They are cheaper than TSC for layer pellets and it is just a small local place, so I like supporting the small local guys. So we buy the big girl duck food there now. With the trio of ducklings, I have Purina Flock Raiser from TSC. Crumbles. Once this bag is gone, I'd like to swap them to a pellet and TSC doesn't have that. The local feed store has a mini pellet food that is 22%. Is that ok for what will be about 2 month old ducklings at that time, or should I mix it with the 16% layer pellets? Tucker Milling, LLC makes the food. And when can I stop providing food at night for the ducklings since they make a huge mess in their house with that.
