Mine is 22 days old. He is eating 6.5 ml every 4-5 hours. I stop at night about 11-11:30. His crop is totally empty by 7 in the morning and I go from there. I still leave just a small amount in his crop for the next feeding about the size of a pea. He is happy and healthy…Hi all, I want to know how many times I need to feed my 14-17 day old cockatiel chicks. Some websites say every 3 hours, while some say every 4 or even 5. Which one of them is better?
