Actually the theory holds that all birds started out flightless... so it's the guys that can fly that are the odd ones.
There are plenty of birds that don't fly and get on just fine.
Most birds can run fast enough to get away from a predator, can jump quite far (some can even run up trees) and reach the ground to peck bugs, grain,
or fruit, so flying is just a plus, I guess raptors would be the exception.
