So I noticed that a lot of people have talked about the differences between Muscovy ducks and mallard derived ducks because they are two species but I haven’t seen anyone saying much about the differences between swan goose derived goose breeds and greylag derived goose breeds. Since they’re two different species I assume the differences must be real and significant. Are Swan goose derived goose breeds like Chinese and African geese louder than greylag goose derived goose breeds like Toulouse geese and Embden geese? Maybe that could account for why people say Chinese and African geese are way louder than other geese. Are there any other behavioral differences? Are Swan goose breeds bigger than greylag geese? And do they lay more eggs? Which is better for meat?
