My cockatiels must be at least over six weeks old. They still eat from a syringe. At first i was feeding them A19 hand feeding formula but now I am giving them mushed bananas and papaya and watermelon. They do not like or notice food in bowls and do not eat bananas that are not mushed up. My other birds (lovebirds, senegal parrots) have all been interested in seeds and fruits at an early stage. Is this normal in cockatiels, what should I do to encourage them eating by themselves?
