Which is more profitable, raising ducks or geese?

If there is a grass source nearby, I think it is more suitable for raising geese. Because if geese have grass sources, the feed cost is very low. The southern market is also relatively large. There is a Luquan Goose Cooperative in Hebei Province that has done a better job in this respect. The anti-season goose breeding they developed has good benefits. You might as well contact them.
