You need to get your feeders out early, late March or as soon as you see one of the birds flying or if someone says they have seen birds. If they don't see a feeder to go to, they will move on to another house. They have just migrated from South America and are hungry. We mix our feed a little stronger than that, we use about a 3/1 or 2/1 water to sugar mix with nothing else in it.
