Simply put, our Quakers should eat as we should. Not as we do, however. Quakers are somewhat prone to fatty liver disease and hypertension, and therefore it is extremely important to offer them only foods that are low in saturated fats and sodium (salt). There is some debate over the ratio in which our birds should eat, but it is somewhere between 60%/40% pellets-fresh food and 80%/20% pellets/fresh food. Your Quaker will probably set its own pace somewhere within that acceptable range.
