I've always wanted geese - supposedly as guards for my chicken flock. But I don't need any more animals here! Most feed companies make some sort of all-purpose poultry feed which should be adequate. If they are laying, a layer formula would be better. I'm sure they would appreciate the hay, but chicken scratch is not a complete feed - more of a treat. If they habitually free-range, they will probably hunt down most of their own food. I hope someone with actual experience can be more helpful.
