Are the American blues and Lavenders real American geese? Or are they a hybrid? I wanted to get a colored goose on the critical or endangered list from the ABLC to raise and found out Holderreads no longer has the Buffs (which I can get elsewhere)...but only Blues and Lavenders which are "rarer" ??????? Would the blues, lavenders be considered on the List too? Or is it only the Buff Americans?
