what kind of parrots are they? i have two parakeets and my best friend has a giant ass moroccan cockatoo.
u can give the baby grinded up fruit and nuts (cashews, almonds, walnuts) and mix it in with baby food that has no preservatives and maybe some water and feed that to the bird. ideally the parent parrots would be eating the food and regurgitating it and feeding it to the baby so they should eat that.
