You'll also need to be aware that the older ones will do their best to keep the young ones from the food. Mine 'solve' this by eating later when the older ones are out of sight. I don't have that much space but do have a building back there that they like to hand around behind. Out of sight, out of mind I guess. So if you see the old ones keeping the babies from the food, don't worry. They'll work it out. Most say to put out multiple feeders by my experience showed me that you could put out 20 feeders for 10 birds and they'd still keep the young ones away for a time.
