When should my baby bird switch from formula to adult food pellets?

The diet being offered currently is not appropriate. At 6 weeks old, Sparky should still be getting a hand feeding formula. A link is included below. Feedings may range between 4 and 8 a day depending on the weight and species. I would suggest having the bird physically examined by a veterinarian or an experienced avian vet to confirm good health. Weaning typically takes place between 8 and 12 weeks of age. At this point, transition to a commercial pelleted diet (Roudybush, LaFeber, Harrison's or Pretty Bird). Introduce other foods gradually and offer a small amount of a fortified seed mix. https://www.kaytee.com/learn-care/pet-birds/hand-feeding

Yes, you can wean him off the formula now. Average weaning is between 7 and 8 weeks of age. I would go to once a day for the next week or so and then do once every other day for a week or so and if all is OK (gaining weight, etc) then you can stop completely. Hope this helps. Best wishes!

AT this age, he should be weaning. Begin introducing a pelleted diet, about 1/4 cup daily to start. Harrison's, Roudybush, Lafeber or Pretty Bird are excellent brands. You may still need to provide supplemental feedings. Monitor his weight closely. You can also offer fresh greens and vegetables as well as a seed mix such as NutriBerries.

If the chick is 3-5 weeks old, he can be removed from the cage. Use an appropriate hand feeding formula and feed 2-3 times daily. The formula should be warm (not hot) as most chicks will refuse cold food. He should also be kept warm. A cold chick will not eat. By 7-8 weeks, he should be eating seed, pellets and other foods on his own.

Alexandrines typically wean between 12 and 16 weeks of age but some may wean earlier. Continue to offer Blue handfeeding formula but don't force him. If he won't eat from the spoon​, make sure he has a variety of foods and fresh water in his cage. Weigh him daily to make sure he's not losing weight. You can also make a mash of the handfeeding formula and leave that for him to eat.

Cerelac is a human baby food, and your baby bird should be on a baby bird food so that he is getting the right nutrients to grow. If he's starting to feather, you can start to add in and offer some mashed up or soaked cockatiel feed/seeds to encourage him to eat a little more since he is old enough to start transitioning.

Thanks for reaching out about Spicy. You could start offering solid foods such as vegetables and softened pellets now. If he is fully feathered, he can have a mild shower/bath as long as it is a warm day in which to dry. Good luck.
