How to feed budgies
Try seeds.
One good option to feed budgies is seeds. However, you shouldn't let your budgie fill up on seeds, as this can shorten a bird's lifespan.

Options are:
(1). If your budgie doesn't eat seeds, simply purchase a small seed tray. You can buy seeds online or at your local pet store.
(2). Don't rush the process if your budgie wants to eat the seeds right away. Then, place the seeds into a seed tray and feed the budgie each seed one at a time.
(3). This is because most seed mixes do not provide sufficient nutrients your bird needs and can cause cancer, obesity, and other health problems. Seeds should only make up 1/6 of your budgie's diet.
(4). Check the seed packets or the small glass seed trays to look for the seeds. The seeds should be placed right between the lining of your budgie's eyes and the top of their beaks.
The answer is:
(3).
