Hi all, I have 4 month old cockatiel, pet store told me it is 4 month old. But I think they lied because it is having first molt so probably 6-7 months old. I have noticed that under its beak and around its eye it started being yellowish. My first thought was it might be a boy but I noticed spots under wing and tail which suggest it is girl. I don't know what it could please help.
