Question: how to tell the difference between a male budgie and a female budgie?
Answer: Once a budgie is a few weeks old, you will be able to tell the sex of the bird by looking at its cere (the nose and nostril area). In normal circumstances, a hen's is brown, and a cock's is blue. The hen's cere becomes enlarged and scaly during the breeding season, and the male's becomes a darker shade of blue. Simple!
