Hi...Um...Im Kiwi,
This is really embarrassing! Why do I have to teach this part? Well I will just hide here in my human's hand while I tell you about breeding. (Im Blushing)

Ok...
so the first thing that you need to do when you want to start breeding is to buy a nice roomy cage for your pair. After all, this is the place where they will be raising their new family.It is best for the pair to have two different sizes of perches so their feet can get the proper exersize.

Be sure to have plenty of fresh water, seed, gravel and a cuttle bone for keeping our beaks in perfect shape. Next is the most important item for you to purchase...the nesting box. You can find them at any pet shop. Make sure to buy the correct size for breeding cockatiels. Take it home and clean it really well with very hot water and allow it to dry thoroughly.This will sanitize it and it will be ready for occupancy.

Next add some pine shavings (you can also find this at your pet shop) to the bottom of the nesting box. This adds some comfort for the parents as they start the long task of sitting (incubating) their eggs. When the pair moves in they will chew the pine shavings into dust so their chicks will not suffocate.

The pair may be afraid of the nesting box at first, but this will soon pass as cockatiels are quite curious little birds. The male will be the first to go in and check out their new room addition. He will then start to coax the female in for a look around. As the days pass you will see the female spending more time in the nesting box and less time out in the cage.

Then they will start the courtship routine. They will kiss, cuddle and groom each other. They might fight once in a while, but what couple doesn't? When the mating begins, the male will stand on her back and they will...well...you know.

And before you know it, there will be those wonderful little care packages that hold each new family member. A hen will usually lay anywhere from 4 to 6 eggs in a clutch. Each egg is usually laid every other day. You should write down the date of each new egg so that you will have an idea when it will hatch. Eggs usually hatch in about 18 days, this is the normal incubation period. The eggs usually will hatch one every other day as they were laid.

It is helpful to place a shallow bowl of water in the bottom of the cage. Once in a while the hen will sit in the water to keep the new egg that she is growing moist. If the egg inside of her dries out too much, she could become what is known as eggbound. This is when the egg becomes stuck in the oviduct and cannot be passed. Hens can not live in this condition more than a couple of days, so this step is very important for your female bird. So then she can use the water as needed.
