One of the keys to keeping birds in good condition is their diet. All my birds are fed a "Green Dish" every mourning which consists of:

• Spinach/Silverbeet and/or
• Endive and/or
• Chickory and/or
• Celery
• Soaked & Sprouted Mung Beans, Wheat & Sunflower
• Snow Pea Sprouts
• Soft Sweet Corn &
• Tip Top 9 Grain Bread

A good seed mixture for cockatiels is a Peachface mix or a Budgie mix with Sunflower added. A small parrot mix usually contains lots of seed that cockatiels will not eat. I feed my birds a seed mix called "AviGrain AA" which I get from Aviculture Accessories here in Sydney. The main ingredients are Canary and Japanese Millet with the seed mix consisting of:

• Canary Seed
• Japanese Millet
• French White Millet
• 10% Grey Stripe Sunflower (15% in winter)
• Hulled Oats
• Panicum
• Safflower

My birds also have access to Shellgrit all the time. I give them Canundra grit with charcoal mixed in with it which they absolutely love. They are also given Cuttlefish bone every now and again which usually lasts only a few hours in a couple of the aviaries.
 

This is the green dish, seed & grit out birds are fed

Greens & Vegetables you may wish to try with your cockatiels are:

• Spinach/Silverbeet
• Endive
• Chickory
• Celery
• Mung Beans
• Snow Pea Sprouts
• Sweet Corn
• Peas
• Beans
• Apple
• Carrot
• Grevillea

You should wash all greens thoroughly before giving them to your birds. Feed greens to your bird at least once or twice a day, as well as fresh water every day.

NEVER give a bird advocado as it will kill them.
