Get a blue ribbon canary mix (high grade mix of seeds for canaries) and a budgie mix and use 50/50 for the birds. The canary mix (different from plain canary seed) has a number of oil seeds in, whereas the budgie mix doesn't have any oil seeds in. The oil seeds are brown and black coloured seeds.
Make sure the birds have cuttle bone, mineral grit and clean water all the time. Change their water every day and twice a day if it's hot. You can add a vitamin mineral supplement to their water each day or every couple of days.
Budgies naturally breed during the wet season when grass seeds are available. You can grow bird seed and when it has green unripe seeds, you cut the seed stalks and give it to the birds. You can also collect wild oats and other green grass seeds from a field but make sure they are free of chemicals like herbicides and pesticides.
You can feed them green leafy vegetables like lettuce, spinach, silverbeet, broccoli, etc. The dark green leafy veges are better than lettuce.

Keep the birds out of draughts and away from heat sources or air conditioning outlets. Cold draughts will kill birds very quickly.
Put a sheet or towel over the cage at night. Have the room light on when you put the towel on the cage and leave the light on for at least 30 minutes after you cover the cage. Then turn the lights out. The birds use this time to settle down for the night and they can't do that if it's completely dark.
Keep the birds out of the kitchen if cooking food or preparing spicey foods like chillis and onions. Spicy food and the fumes form onions can kill birds. Birds have also landed in pots of boiling water, in woks and flown into hot open ovens and been killed. Keep the birds cages when cooking food.
Keep the birds away from cigarette smoke, bug sprays, deodorants, hair sprays, air fresheners, paint fumes or anything else that creates fumes. Birds die really quickly when exposed to fumes.
If the weather is fine and warm, put the birds outside in a shaded area. They can have morning and afternoon sun but keep them out of hot midday sun. If the weather is really cold, keep the birds indoors. Don't move the birds into a warm room and then put them outdoors in the cold. Give them a stable temperature because sudden changes in temperature will stress them and they get sick.
---------------------
If the birds get sick they will puff up their feathers and their tail might pulse (move up and down a bit). They get poop on their feathers around their butt and they might sneeze or have a discharge from their nostrils. If the birds show any of these symptoms, keep them warm (32-36C) and humid and contact a bird vet.
---------------------
Male budgies have a blue cere (the nostril area above the beak) and the females have a brown cere. Female parrots bite much harder than males. This is because they have to defend the nest from snakes, lizards and other birds. If you pick up a bird and it latches onto your hand and tries to draw blood, it's probably a female.
Budgies can breed when 3 months old but it is best to wait until they are 6 months or older. They lay around 3-5 white eggs that hatch after about 3 weeks and the babies fledge (leave the nest) about a month later. A standard wood budgie nesting box is suitable and you can put a thin layer of course sawdust or fine wood chips in the bottom of the box. Budgies make good parents and will breed readily in cages and aviaries.
) Kiwi is a loyal lovely bird. He recently went through his first molt. I was really concerned because he was loosing feathers and he looked slightly bedraggled. However in the past few days I've noticed they are growing back! He is looking fuller and a lot more colorful.
