I have been googleing a lot trying to find on. But without success...
I hope that one hk breeder will come accross my post and will contact me.
In mean time I keep on looking.
Any idea how to recognize approximatively the age of a cockatiel......
When male grey cockatiel are young, they looks like female, when it is older, they will have a yellow face with bright orange cheeks, with a dark grey body. Female grey cockatiel will have a grey face, and a lighter colour of orange cheek. That's only to know if its a baby or a mature. Not sure about the actual age. Sorry. A blood test will be the best way to find out.
Once the bird matures a bit, males Cockatiel will start singing right around 3-4 months old. Female will make sounds but doesn't sing nothing like a male.
