As the cockatoo gets older it will generally become less expensive over time. Buyers like that and pay a good price for it. A cockatoo that has just been weaned of its formula is young, strong and usually still a pretty docile and sweet animal. The price of a young adult cockatoo is the highest of all the ages. A baby cockatoo is much more vulnerable than an older cockatoo.
You also take all the responsibiliy and risk on you, because of the baby cockatoo gets sick you will have to pay for the vet. If you buy it as a baby, you will take all this work on you and this will save the seller valuable time.
A very young baby cockatoo is often cheaper than a young adult cockatoo because it takes a lot of work to raise the baby.
The age of the cockatoo is a strong determinant for its price.
