Is anyone around an expert on brown chinese geese?

UPDATE
These 3 lovelies are now 28 weeks old and we still have no idea if they are males or females
Just wanting to know if we have 3 males, 3 females or a mixture

Any one have any guesses with these pics ?

Pic 1, back one looks like a gander knob with the roundishness. Not sure about the one in front. Pic 3 looks like a hen.

Awesome we've been hoping we had at least one of each! 2 of them do look like their knob is slightly smaller and different to the other. You mention the roundishness of the knob, are ganders knobs rounder then females ?
Sucking up all the experienced information i can

i'm seing a big difference in body-type between my two goslings. the taller, pickle, seems to have a higher center of gravity. while the shorter, tilda, is lower & her abdomen is more rounded. thoughts?
