Johnston & Jeff Peanuts for Wild Birds are aflotoxin tested and free from mould and infestation. Only the best varieties and grades are selected, many are human grade.
The higher the calorific values the better. Some wild birds have to eat their own body weight in food per day just to survive. So the better quality the food, and the cleaner it is, the easier it is for them to metabolise it and the better they do. It is for the reason alone why Johnston & Jeff take such care cleaning and choosing the best peanuts.
