The Zebra Finch is tiny, but is not the smallest of the finches. It gets its name from the zebra-like stripes across its neck, chest, and especially from its black and white barred tail. 

Zebra Finches breed readily, and are a good beginner’s bird, easy to care for and requiring a minimal time commitment. Because they are generally kept in pairs, your Zebra Finches will not need you to keep them company 

Most Zebra Finches will not want to be handled. They are not really “trainable” as a parrot type bird is. Occasionally you can find hand-raised finches, or you may have to hand raise a baby yourself. In those cases you will have a finch that is bonded to humans, and will happily perch on your shoulder and be perfectly comfortable. Never try to force a finch to be “friendly” – you will only result in terrifying it.

They are dimorphic. Males and females can be
easily distinguishable with their colouring patterns.

Male:

The “normal” colored male (the most commonly occurring color) is grey with a black tear drop at its eye, bright red rouge patches on its cheeks, and a bright red beak at maturity. 

Female:

The female is more muted in color, with its beak being a paler orange. 

Zebra Finches come in a variety of mutations, including pied, fawn, cream, white, and others.

Breeding :

Zebra finches are easy to breed. 

The male Zebra Finch does sing, but more likely you will hear a lot of “peeping” from your pair. They sound like tiny little car horns. While they will vocalize all day if they are happy, they are not loud, and their voices are quite pleasant. If you are able to keep them outside, or by a window where they can hear birds, they will often respond to the wild birds calls.

Finches are not long-lived birds, living only about 3 to 5 years, and if you’re really lucky, a bit beyond.

Above details are what I got from others what they said. Now comming to my experience

Yeah ofcourse they are easy to breed. Though their sound is low they are fine. And they often try to do the notes of other wild birds too. They get pretty easily alarmed even when hands go close to them. They like bathing. I have uploaded this video to show how well they like to do bathing. Keeping two bowls of water is advisable. One larger and one smaller. In that way they will use bigger bowl for bathing small bowl water for drinking.

They do love egg shells apart from small grain. Boiled eggs shell pieces can be given to them for eating. Two nests were placed inside the cage, and i just dropped some coir fibres which they took to the nests and used them inside the nest.
