Are they the same age?

Your probably right, maybe it was a different breed that gets to 30.I have read that they can be a bit over 20 pounds. Never heard of them hitting 30 but I'll bet it's possible.
True Brown Chinese have much larger knobs, have very upright posture, and a long arched neck. The geese you described are probably Dewlap Africans crossed with Brown Chinese, several generations ago.I've read some in the beginning of this thread about the differences. What about the brown Chinese differences? I've seen some hatching eggs for sale recently saying they are brown Chinese, and the pictures of the parents don't have the very long neck, but look more like what is called African without the dewlap, or am I mistaken, and they are just a different strain of Chinese. So I wonder what they really are. I suppose if I like how the parents look it doesn't matter, but would be nice to know.
