I don't think they trust you right now. I would say let them out of their cage. They'll come out on their own and in my experience with budgies, unless they're really adventurous, if they're still scared of you at the moment they'll usually stick to one spot if they're out of the cage as long as you don't go over there and try to hand train them if they're out so that they spook.
It doesn't matter much to me of they do that because i'm in an apt
For you it may be different.
