Exactly.Even with the "see but no touch" method the chickens will probably get into a few fights in the first week(s) since they can't form a pecking order through the fence. As long as they don't hurt each other seriously you'll have to let them do their thing.
Just make sure to offer feed and water in multiple places so that every chicken gets the chance to eat and drink.
Pecking and attacking will be normal. How would you react if a random person barges into your home and makes themselves at home>>? lol

That's how the established chickens feel. They need to let the newcomers know that they're the boss, so let them fight and peck unless it gets really bloody.
