Pretty Bird African Special might be larger than your Ringnecks like. This food has a higher level of Calcium in it which is good for African Grays and breeding birds. You should get your Ringnecks off of a seed only diet. I would suggest a diet with pellets, fresh fruit and veggies, and some seed and nuts as a treat. We feed our birds peas, corn, Lima beans, black eyed peas, cauliflower, and broccoli. We buy these frozen and heat them in the microwave. Just make sure you let them cool to about 100 degrees before feeding them. They also like foods from the table including pasta, potatoes, and pizza. Experiment but remember to not give them excessive amounts of fatty foods. We usually give them little bits of whatever we have for dinner. Keep pellets in the cage 24/7. Feed them soft warmed veggies and fruits twice a day. Make sure the veggies don't stay in the cage for more than 4 to 5 hours and never overnight. Remember Parrots are picky and some things might be rejected but always keep trying and you will be surprised how easy it is to get them to eat good healthy foods and treats.
