I have sebs being shipped tomorrow. I ordered 10 but am only going to end up with 7 it looks like.... But 7 mouths to feed is still a whole lot! What do I feed this guys to start out with? Should I be feeding a waterfowl food or a chick starter? I want to make sure they get what they need nutrionally. They do sell mazzurri waterfowl food here,but it sure is pricey. If thats the best for them I'll pick it up tomorrow! Forgot to add that they are between 2 days and 6 days old.
