Food can be placed on the floor of the cage in a dish, tray or bowl. A feeder secured to the bars is the more usual arrangement in a smaller cage, with a mixture of feeding stations in a larger enclosure.
Parakeet Food Dish
The feeding bowl needs large surface area – parakeets will only eat the seed they can see, and are unable to rummage through deep bowls to find the uneaten stuff beneath. A centrally-placed hopper is ideal, enabling several birds to feed there at once. Remember it needs to be easily removed from the cage at least once a day. Avoid placing the food bowls beneath perches, to prevent your parakeets from pooping in the food.

You can have a variety of food bowls and feeding stations in a larger aviary
Parakeet Seed Feeders
The feeding dish needs to be secure, so that it can't be tipped or dislodged. It also needs to be easy to clean and easy to get in and out of the cage. For smaller cages, you can buy feeder-protectors that clip above the food bowls to prevent them getting soiled with bird droppings.
Many feeders are simple free-standing or attachable bowls. A seed hopper is another variation, a simple way of enabling several birds to feed at the same station at the same time. Hoppers are the best way to feed pellet food. With seeds, you’ll need to blow the husks from the hopper to make sure your birds have constant access to the fresh stuff.

Hi, WARNING to any other novice budgie owner like myself, please be aware of buying individual large seeders for only one budgie, thinking I was giving my budgie the freedom of eating as and when he wanted, plus saving me the daily chore of emptying his feeder each day, as it advertised the empty shucks falling through the grid, resulted in him becoming overweight, which in turn has left him with LIVER damage, thankfully due to this forum and advice given, being told that veterinary advice was needed he is now on the road to recovery.
