You can try some very fine chopped lettuce as long as you have chick grit down for them they need to have grit when eating anything other than their crumble.Put the grit into a separate bowl from the feed. They will eat it as needed.Does anyone know of any treats I can feed my one week old duckling or should he just be on crumb right now? I'd love to give him something new as he wants to eat anything he sees xxx
