I've gotten the same responses from experts (avian vets I called).
They say that birds cannot digest yogurt and will cause diarrhea
and maybe death. The enzymes and bacteria are designed for humans,
not fowl.
One of them told me that she has had to put down many sick birds that
could be saved but, the owner fed their birds (parrots, chickens, etc.)
yogurt and caused them to to waste away based on silly Internet rumors.
