I have three young ducks who have been raised on the regular mixed flock Grower feed. They are about three months old now. I also have two one year old ducks that are laying an egg a day, that I got from a farm recently. I would like to switch my ducks to organic feed but the only kind of feed Tractor Supply has for "ducks" is the regular "flock grower" which they should not need forever. TS has organic pellets but they have pictures of chickens only on the bag. Would these be okay for ducks?? I seem stuck with the flock grower forever if not... My ducks have a large area where they can forage all day long on plants and bugs.
