You can easily make your baby budgies tame.
People are willing to pay more for a tame budgie.
A budgie who is used to being handled will be less likely to be traumatized by vet visits, etc. Friendly pet budgies are more likely to make their owners happy, resulting in a happier life for both budgie and owner . Baby budgies who are handled daily in the nest turn out as tame as the hand-fed ones. This has been my personal experience, having done both handling and hand-feeding. It takes about 20 to 30 minutes of handling daily to get tame baby budgies.
