Females are usually a little duller than the male, with a paler chestnut breast and less pronounced black band dividing the chestnut and white areas of the underparts.

Eggs: A normal clutch is 4 to 6 white eggs, each approximately 12mm x 17mm, exceptionally 3, 7 or 8 eggs. Incubation period is 12 to 13 days. Incubation is shared by both the cock and hen, and both birds remain on the nest at night. The parent birds cease to brood the chicks when they are approximately a week old, especially if the weather is warm at the time or they are housed in a warm bird room. The young fledge at about 21 days. Young in captivity return to the nest to roost for some nights after fledging.

Diet standard finch mix, and a bowl of clean water. Every day they are given either soaked (sprouted) seed and/or egg food Spray millet is provided 2 or 3 times a week, and they also receive mealworms and/or wax worms once a week, unless they are feeding babies, when they receive mealworms and/or wax worms daily.

They are usually good parents, and a typical clutch will consist of four to six eggs, and incubation is 13 to 16 days. They will leave the nest about 3 weeks later, and the parents will continue to feed them for another three weeks. Adult plumage is obtained three to six months later.
