I'm pretty sure my Africans will not have dewlaps. I just looked at Metzer's site and their Africans are pretty dewlap-less. I am so bummed. Still love my geese- but bummed!
Did you purchase their Super Africans or the regular Africans? If you got the Super Africans they should get dewlaps, but if you got the regular Africans they will most likely not have any sort of dewlap.
