My pair of gouldian finch have a brood of 3 chicks. The chicks are about 15 days old and quite demanding. Recently I have noticed that the male is becoming aggressive to his mate and not allowing her to feed or sit in the nest. She wants to feed her chicks and care for them but everytime she gets close the male chases her off and starts pecking at her.
You absolutely need to separate them as soon as possible.
A male can become so aggressive he may kill the female.
He wants to keep her mating with him. Not sitting on the eggs or raising the babies.
Please remove him to another cage as soon as possible.
Males will sometimes attack and kill their own chicks as well in order to keep the female mating with him.
It's horrible, but sadly true.
Hopefully, since the aggressive male has calmed down, he will continue caring for the babies and refrain from being aggressive with the female. Although this will not help your current situation, I would suggest that you buy some Society finches and read up on the process of having society finches incubate the Gouldin's eggs and raise the babies once the eggs hatch.

Ok from what my dad told me... yeah, he kept zebra finches (among other birds, a personal favorite would be a parrot called Showoff). He said not to worry unless it is habit. They can use their own feathers to make a nest if need be.
Finches are popular as pets in part because they breed well in captivity. These pretty little birds will provide you with many joyful hours. There are lots of questions that arise from bird keepers.
