We bought three geese this spring. Two turned out to be Toulouse, one is either Brown Chinese or African, I really can't tell what it is. Lucy is definitely more petite than the two Toulouse. Lucy is smaller than the two White Chinese we we have that are 6 weeks younger too. How can I know if Lucy is Brown Chinese or African? She/he is quite petite compared to the Buff, Toulouse, and White Chinese we have. Does that point one way or another?
