Now that I look at mine they are 20 Cc too but I don't feed by measuring the amounts because even with this product quite a bit gets wasted. I feed as much as the baby wants until it's crop is rounded but still soft. They can overfeed, regurgitate and aspirate if you fill the crop too full. Its a good idea to weigh the babies before and after feeding to find out how much they ate but trying to adhere to a strict time and volume schedule can be a mistake. Parent birds feed small amounts when the babies beg. They sleep between feedings. I never wanted my babies to cry for food and not get fed because I thought it would harm the trust and cause feeding stress. When they first hatch their crops are tiny and the formula is runny, so the crop empties pretty fast. Every two hours I would feed them round the clock. As their crops get bigger they can go longer.
