Adding an extra feeder can help with that. Mine is behind a large log across the run from the main feeder. It's not a big one, just enough to let the more timid birds, like low-order hens and acclimating youngsters, eat in relative peace.This is exactly true.
You also need to montior the "lieutenant" closely. Just because he isn't being torn up in a fight, doesn't mean that he isn't being neglected. Sometimes the alpha won't let the beta eat.
We recently had a transition of power here and it was really kind of sad. We had an alpha rooster, whose name is honey for years, and a very awesome new hatch one year old, clearly has taken the helm. He was, and still attempts to food starve Honey.
