The products included in this category make it possible to cover the needs that cannot be completely covered with the complete foods, or those that are not usually covered in diets based on seed mixtures.
This is the case, for example, of flint sand or calcium grit. Our complete foods contain flint sand and calcium sources, but only the amounts to meet the general needs. In order for the birds to be able to self-regulate and more precisely meet their real needs, it is essential that they have Silex Grit and Calcium Grit permanently at their disposal.
Other supplements are designed to facilitate the preparation of sprouts.
