Is my Budgie lazy or sick?

[bigbuggy]

Good day all.
I recently got my first budgie, Lapiz!
I got him at an ordinary pet store and the assistant told me that he is an english budgie.
It has been about 6 months now since i got him, he is kind of use to my hand, which is good.
But i am a bit concerned because often we open the cage for him and he doesnt want to go out. He isnt really that scared of us anymore so im not sure whats wrong.
I even built him a lovely tree playground with many toys! I also place millet and lettuce on top to lure him but he is more interested in sitting atop his perch.
His behavior otherwise is normal, his droppings are normal. im not noticing anything concerning that shows me he is sick. Im just wondering is this normal? Or am i doing something wrong.
Sometimes he is active and will climb out, but he usually only sits on top of his cage. He never explores and flies around(except when he gets accidentally spooked).

Welcome! I hope we get pics of Lapiz 😊

Someone will be along with good advice, I'm sure. In the meantime, my thought is that your little buddy could use a feathered friend to inspire him but I'm sure there are other things to try.
It's good he has a playground - is it possible to introduce a forage area where he can root around for treats such as sprouting seeds? Foraging can be fun and stimulating for budgies.

I assume his appetite is good and his droppings a firm and of good colour, no sign of laboured breathing or bobbing tailfeathers, etc.

The cage becomes a safe haven for some birds, and the exhibition budgies are not known for their activity - they are bred to sit on a perch and look pretty not fly about like little spitfires. Unfortunately! There are a few things you can do to entice him to come out, as in a perch or landing platform just outside the cage door with a little millet hung up just outside for further enticement. If he is happy to sit on a finger, or a perch, get him to step up and then gradually bring him towards the cage door. It may take a few time initially, but continue to encourage him out of the cage. Most times, a bird who is reluctant to leave the safety of the cage will gain confidence the more they are out as often it is the fear of the unknown that prevents them taking that step out. Once they get to know the layout of the room they are happy enough to come and go on their own terms.
