My geese, ducks, and chickens get Nutrena Country Feed All Flock with 18% protein. Mostly my geese eat grass and nibble feed. You can always add Niacin.
I don't know what geese eat/need.
May I ask where you found this feed?
I've not seen this brand name before.
I am adding these two to my Google sheet now...thank you for posting these labels!
A thing to note: geese as backyard flock aren’t entirely gamebirds. They teeter on the edge of fowl and gamebird. Are they fully grown? If not, neither has enough protein.
I have never used gamebird feed for my geese. Growing birds need about 16-18% protein, maintenance runs more like 12-16%. I feed a mix of mazuri maintenance (16%), flockraiser (20%), and whole corn (9-10%). I feed approx. 1/2-1 cup per goose 2x daily. This is only to supplement their primary diet of grass (summer) or grass hay (winter).
Rather than use gamebird feed, I recommend flockraiser (available everywhere) with a mix of whole grains, like corn, oats, wheat, etc.
