How do you even have pet bird

I don't like having a cat or a dog as a pet

Rather a bird of any kind

I always get the bird before even hatching or while it's still a chick. Raising it until it's old

I spend time with it, playing and even feeding it on hand

Yet every time I get close or walk to them

They just run away or flap their wings away from me

Snacks? Yes i do. Toys? Absolutely

Only one i raised a duck but i failed to 'befriending' it and ended up getting bitten every time it sees me
