So we have TONS! of left over stuffing from Christmas. It has gluten free bread, celery, sage, sausage and onions. I have read onions are not good to feed because it can taint the flavor of the eggs but also contains toxins in them that can damage red blood cells (or so I read somewhere else). But I was wondering if cooking them changes that. I mean the stuffing is mostly bread, but if I can feed some of it to them safely I would like to do so instead of composting it all.
