Hi there and
to the forums!
Your budgie is a very sweet little girl, but you should never breed your budgies without doing all the proper research first.
Budgies are not guppies and putting two in a breeding cage without having an actual background in the proper methods and practices could be disastrous. By breeding your birds without researching properly, consulting with an avian vet, adjusting their diet, etc., you are putting them in danger
There are a lot of complications that can result from breeding budgies such as nest abandonment, egg binding, chick abuse, malnutrition, stress to the parents or chicks, etc. Please reconsider breeding your birds until you've done the proper research in order to give your birds the best chance to live the best life possible
