CAN I TAKE THE BABY BIRD HOME SO THAT I CAN FINISH RAISING MYSELF

No, we do not, under any circumstances sell UN-weaned birds. You will not get a better bond with the bird by finishing off the weaning process yourself. A baby parrot will not stay with its parents in the wild after weaning, once it leaves the nest, it goes to find new friends and will actually bond and respect their new friends more than its parents. This is the same for Hand raised birds; the new owners will have a closer more respectful bond with their bird then we would being the human parents.
