budgie gender

I have had my budgie for 4 years and have not been able to determine it’s gender. Usually your supposed to be able to tell by the cere, but it changes so often I’m not sure what to think? Any advice you may have would be great.

Hello. Can someone help we with a gender of my parrot, please! ?? Thank You!!

Hello! I've recently bought my budgie Turkey and I adore him! The pet shop i bought him/her from told me Turkey was 3 months. I had done my research and I didnt think he/she was 3 months old. But in good faith, I believed them and would have bought Turkey either way. What do you guys think...
