The purpose of this forum is to promote the best practices for the health and well-being of budgies.
If you wish to keep your budgies healthy and happy then you must make changes in the way you are caring for them.
Allowing them to breed at this stage in their life is not showing love for them. It is putting both them and any offspring at risk. The female's calcium levels will be depleted to the point there will be no way to correct the problem and both birds will be exhausted physically and emotionally if you allow them to continue as you have been. On top of this, the risk of any offspring being weak, underdeveloped and unable to thrive is magnified immensely.
Please take the advice given and do everything in your power to ensure the budgies do not breed again.
Follow the advice in the link on how to discourage egg laying.
If you are unwilling to do so, then the members of this forum will be unable to help you.
Rearranging their cage frequently, and limiting the light they get to 8 hours a day will help tremendously. Please be sure you never put a nest box or anything that could be used as a nesting site in their cage.
When they come into condition, limit the amount of protein in their diet at that time.
You've come to this forum to ask for advice and you've been given the best advice possible under the circumstances.
Now it is up to you to ensure you do what is best for your birds' health and well-being.
