Heh. I guess it’s a regional thing… we had “banny” chickens. At least that’s the way we pronounced it. Meanwhile, they were Bantam chickens in real life. But maybe there is such a thing as a Banny chicken.
It’s sort of like how we used to call a Brahman bull a “bramer” (sounds like bray-mer) bull. I was probably 16 years old and was at the Houston Livestock Show and Rodeo and saw a leaflet that had a picture of a Brahman bull. I thought “they’re high – that’s a bramer.” But later I realized that our family was probably single-handedly destroying the English language. Ha.
