Has anyone here heard or read that there is a "conditioner" used in some breads that is mostly ground up feathers? Mostly white breads, I think. And the preservatives! We left a loaf of white bread on the back porch. (We don't eat white) It did dry up some but never did turn green and still lasted a year. Finally got tired of looking at it and gave it to the birds. Our birds won't eat some brands of bread. Then we had to give it to the donkey. He'll eat anything (Well almost anything)
