I can manage the phrase "Buh buh huh?" which seems to have a multi-situational greeting aspect, not unlike "Hey, what's up?"
I probably use it for the wrong things sometimes. Hence the perception I'm not very smart. I wanna be goose-lingual.
Either chickens' language is very simple and I've managed it, or chickens are much more forgiving of idiots amongst them. "Oh, isn't it cute, she just aked us about our feathers again. What should I tell her this time? 'Yes, Food Lady, feathers REAL good for Chickens. Feathers GOOD, naked BAD. So sorry you only have them on your head." [Aside: "Nobody tell her her feathers are even more useless than the silkies'."]
