In order to breed, canaries should be kept separately before pairing, and when they kiss each other with their mouths in cages, they should be put together in breeding cages. When the male and female birds live well together, they can hang the artificial nest above the breeding cage. When the female bird's beak feathers swim or swirl on the nest, it means that nesting has begun. Clean cotton should be hung on the cage post, and birds will soon take it to nest. 3-4 days after nesting, females begin to lay eggs, with 2-6 eggs per nest.

The canary was hatched by a female bird. Because females lay eggs every day 1 piece, the chicks have different time. In order to overcome this deficiency, in some places, after female birds lay eggs, fake eggs made of gypsum are replaced with real eggs and stored. After four eggs are laid, the fake eggs are taken out, and the first three real eggs are put back in the nest for the birds to hatch, so that four chicks can hatch on the same day. On the sixth day of incubation, the eggs were examined under the lamp, and the unfertilized eggs were taken out, and then re-examined after 10. Incubation 14- 16 days.

Young birds can't feed themselves without their shells, and they have to be fed by their parents. Yuyao is nutritious and digestible food and water such as egg yolk noodles and cabbage. During the brooding period, feed a piece of fresh egg yolk every day, and pay attention to whether the parent birds feed the chicks. Generally speaking, chickens will not starve to death if they don't eat within 24 hours after hatching. If the parents still don't feed them the next day, they must feed them manually, that is, mix the egg yolk and vegetable juice into paste, pick up the egg yolk paste with a small bamboo stick and send it to the chick's mouth until the chick is full. 1-2 days later, if the parent birds start feeding the chicks, they can stop artificial feeding, otherwise they will stick to it until the chicks can peck themselves.

It takes about 25 days for chicks to hatch until their feathers are fully developed, and they should be fed with egg yolk noodles every day. After 1 month, chicks can be raised separately from their parents. At this time, the feed is still mainly egg yolk powder, and chicks can gradually change to daily feed after 2 months of age. Most females begin to mate and lay eggs again after the chicks hatch 12-2 1 day. At this time, the female will drive the chicks out of the nest, and if the birds refuse to leave, they will be ruined. At this time, in order to protect the safety of young birds, it is necessary to add an artificial nest in the cage, put cotton or fine bamboo clothes in the nest, and let the adult birds clean up their nests themselves so as not to drive away the young birds. After 6 months' feeding, chicks began to sing and reached sexual maturity in 9- 10. Goldfinch can only learn to sing well under the guidance of an old bird who is good at singing. Old canaries, larks and big tits are all good singing teachers, and golden finches can also teach them to sing with good records or tapes of singing birds. Be sure to teach the golden finch to sing from an early age. It is generally believed that it is no longer "catchy" after molting for the first time.
