Hi Kris, congradulations on choosing a budgie, they make wonderful pets. Your birds will feel strange and scared for a while. I usually offer millet hung in the cage for new birds. Millet is not as healthy as the seeds but it is a good way to have them eat and start to feel comfortable with their new surroundings. Also try placing pieces of apple in the cage bars or a piece of romaine lettuce (budgies love lettuce).
Biting is usually a fear factor, so I would go slow and just start by sitting next to the cage and talking quitely with your new bird then as time goes on try placing your hand in the cage and not moving it so the bird adjust to the presence of your hand and learns that it is not a threat to it. Eventually you can leave the door open and it will feel confident to come out.
I breed baby budgies and clip the wings of my babies. You may want to have the wings clipped, this does not hurt the bird and can help in training it. When it flies it will quickly guild to the floor and is easier to retrieve then if it is fully flighted.
Go slow and I am sure it will develope into a wonderful pet.
