Your prized cockatoo has been incubating her eggs and the new babies have just hatched. They seem so helpless – naked and blind. Soon you will see many changes as they begin to grow. Here is a quick overview of the developmental milestones in your cockatoo’s life.
Cockatoos are born blind with their eyelids sealed shut. By the time they are 10 to 21 days old, the eyelids are open and the bird begins developing his vision.
Cockatoos are one of the few bird species whose ears are open at hatching.
Cockatoos are born with a sparse covering of soft down. This down slowly comes off the bird in the first week of life. Feathering then begins and develops symmetrically. Pin feathers develop after about 1 week of life. Initially, feathers develop on the head, wings and tail. Slowly, the pin feathers are replaced by adult feathers. By 4 to 5 months of age, most birds will be fully feathered. This will vary a great deal from species to species and even from bird to bird.
Many psittacines are banded for identification. This leg band can be placed on the leg at around 3 weeks of age.
By the time the bird is 14 weeks of age, he will start leaving the nest box. At this point, weaning begins.
When baby birds are born, they aren’t the most beautiful creatures. Weighing around 15 to 20 grams, it is sometimes difficult to believe that the baby will grow into a stunning cockatoo. Baby birds are born with thin chest muscles and a protruding gizzard. The baby also sits on his hocks. This gives the baby a tripod appearance, which is the only way they can stand upright. In the first couple of weeks of life, the cockatoo can barely hold his head up. He will sleep in a crouched position with his head touching his feet.
Over time, this unattractive and weak baby will gain strength. He will slowly be able to support his own body weight. His legs will develop beneath him, giving him the ability to stand. Within about a month, you will begin to see the early signs of how gorgeous your baby will be.
