there's some muddiness in the way the "african" term is used.
I've got 3 brown chinese and 1 african - the brown chinese are 4 months older than the african, and (he's maybe 4 months?) - and at the moment I can't tell my smallest brown chinese from the african, they look identical. I don't know how much bigger he'll get, and he's got the long neck like the chinese.
my guess is they may actually all be brown chinese... nevermind that one was sold to me as african. I think it's pretty common to order "african" at some hatcheries and get what's really brown chinese.
the super african and dewlap african do look different than than what's commonly sold here as "african". the "super" birds have the dewlap, shorter neck, and they should be heavier.
roboboy, are those white chinese on the left of the second photo and in the center of the third photo? that's the shape and neck my brown chinese have. your africans look MUCH bigger bodied than those. if your whites are white chinese similar in size to my brown chinese, I think I'll have to order some super africans next year. I don't love the dewlaps, but it would be fun to have "draft horse" sized geese...
