Well , budgerigars in the wild often have to fly daily anyway to survive. If it is domestic budgies your talking about the answer is NO. if they are kept so you ytake them out of the cage they need to be TAKEN out daily but they do not need to fly, they prefer just sitting on your shoulder.
they fly into small places where predator cant fit
Budgies do not soar. They fly, and to do so, they must flap their wings.
yes budgies do make nests if the budgie is in the wild it will make a nest in a hollow or branch. if it is in an aviary/house it will make a nest and lay an egg everyday in a nesting box (if provided)

This question is a matter of opinion. Some people like English budgies better than regular budgies or other people like regular budgies better than English budgies.
Do not order your budgie too much. they are not children, but wild birds that have been rased to be tame. they still have wild somewere in them, and they have feelings. don't abuse the fact that you have a tame bird. All my budgies are wild. be carefull with the bird.
