I have one duck living with three chickens. I am currently feeding them Purina Layena (18-20% protein) pellets, and Family Farm cracked corn. I recently found out that the layer pellets I'm giving them is not suitable for ducks unless I supplement it. How should I feed her? Would it be safe for the chickens to feed duck food? Or supplementing the feed with something safe for the chickens? Maybe some type of food that works well for both species. I don't know if I could manage to feed them separately. Any advice? If you need any more information, just ask! Thanks!
