Thanks, guess I am going today to pick up this box of buggy beans,
I have this image of really gassy birds....
LOL.
Beans give people gas because they contain a protein our stomach does not have an enzyme to break down, so it gets all the way to our intestines, where there are bacteria that have no problem breaking down that protein, but they produce the gas as a by product. Birds do their "fermenting" in their crop before it goes to their stomach, so they might belch, but are not likely to get gassy.
