Is my budgie ok?

Hi so I adopted a budgie from petsmart about two months ago. I love her very much, she gets out of her cage once a day for about 1 hour to 30 min. She's super sweet and really friendly. Her name is angel. Anyways, Whenever I go to take Angel out she shivers a little. I've read that shivering is a sign of illness and I'm worried. Should I take her to the vet? There is one close by but I'm hesitant to go there because he broke my last bird's leg when taking off the leg band. My last bird was so stressed out from the splint that he died. It was really sad. So, should I take Angel to the same vet? Should I even take her to the vet? She seems fine other than the shaking as she is eating and drinking normally, her poop looks fine as well. Ok thanks! Also any recommendations to caring for her will be appreciated as well because I'm fairly new to owning budgies.
