Those are wattles, some dairy goats have them, some don't.a lot of them had the the things that hang down under their neck on both sides. what does that mean?
I've yet to see a Nubian with them (but suppose it's possible), it's usually the Swiss.
There's tons of articles out there on wattles and genetics...personally I don't like them, but they're harmless.
