It is a shame that feed stores do not really know how to feed geese properly. They keep telling people to feed chicken feed. Geese have different needs than chickens. If you mix your own feed you can use oats, wheat, barley and if possible find a Tractor Supply Store and get their all flock. Then mix in the oats, wheat and barley along with animal brewer's yeast. This will be a much more stable diet than cracked corn. I would only use a tiny bit of corn because it is just not nutritious at all for the geese. That is more of a treat not a food source.
