Within the first week, you will start to see some feathers developing. These are the pin feathers that look like simple shafts. At the 10 to 14 day mark, the baby cockatiels appear quite a bit bigger and are four to five times their original size.
In general, 3-week old cockatiel babies usually require five feeds per day; 4-week old babies require four feeds; 5-week old babies need three feeds daily; 6-week old baby birds are usually down to two feeds per day; and 7 week-olds usually require only nightly feedings until they are weaned at 8 weeks of age.
