It really does not matter about the roosts, or the hiding spaces, this is not a peaceful flock. It is very disheartening to be with a flock in this state of turmoil. Pull one of the younger birds. Try pulling the bully first, if another bird starts attacking the victim, then put the bully back in and try pulling the victim.
Usually one of those solutions will work. Being raised together means nothing to chickens. They are not wired like that. If one of these work, you need to remove the other from the flock. Not all birds will fit in any flock and set up, some will never fit, no matter what you do and to keep trying causes a lot of strife, which is very hard even on the birds not part of the fight.
Once they start laying, they usually are accepted by the older birds, so it surprises me that they still are not.
However, always solve for peace in the flock. Wishing they will all be nice will not work.
