Maxollie, thank you for an explanation.
Sorry, I am from Slovakia, not from America.
And I had my dearest Bilko from 14. 3. 2013. So you made a mistake. My previous budgie male Kukuciacik ( Ciacik ) was about 13 years old. But Bilko could be much older then just a very young, when I bought him 14. 3. 2013. How do you feed your budgies? With what?
