My keets seem to really like the Lafeber's pellets, they smell very sweet so i wonder if that's why they like them so much. I didn't have to crush them or anything odd like that, they just ate them.

Most veterinarians i have spoken to suggest a mixture of seed, pellet and fresh fruit/vegies. I feed an 80/20 pellet/seed and offer fresh stuff daily.
