Hagen Pro-Mix contains the highest quality seeds blended in nutritional balance for all medium and large companion birds. This safflower-based staple seed diet has very high palatability in a broader range of grains.Pro-Mix encourages ingestion of a wider variety of seeds because of its reduced sunflower content. It is supplemented with vitamins and minerals on a special (hulled) carrier seed. The regular use of a balanced vitamin supplement such as Prime may help prevent nutrient deficiencies if the bird becomes selective about the seeds it eats. 1.13 kg (2.5 lbs).
