Hello:) I am new to breeding and even though I thought I had done enough research I still am feeling a little lost:(... Snowy (male) and Daffodil (female) have two gorgeous chicks, one has just ventured out of the nesting box. However Daffodil has laid another 2 eggs, she seems okay but I am worried what should I do and also how can I stop this happening to other couples? Thanking you in advance

It is recommended to let budgies have 1-2 clutches.

If you are wanting to stop this, just remove the eggs from the nest once you notice them. Once the babies have left the nest, block the hole or remove the box so the female can no longer get in.
