I bought a budgie about 2 months ago. He is about 6 months old and I have spent a lot of time trying to tame him. I searched everywhere online and followed the steps but he won't become tamed! I bought him from a petstore so I know it would be hard to tame. They told me it would take about a week to tame him. He takes food from my hand and can go on my finger, but he is always scared. He is timid and shy but he doesn't bite. My mom told me by now it would be impossible to tame him unless a miracle happens. I don't know what to do and I feel like giving up (selling him). Can anyone please help me or give advice?
