Try this: let the older birds out to free range. Then put the chicks into the older girls set up. Lock them in there. Let them explore for most of the day without being chased by the older birds that are out free ranging. This allows the chicks to find some safe zones. I have even chased them a little so they find the hide outs.
A pallet on a single layer of cement blocks, where chicks can get under but slows down an older chicken. A one way gate where chicks can fit through but older birds cannot follow will really help. The chicks then explore and get brave on their terms, not human terms, and can retreat to safety.
Then I would I would lock the big girls up in what was the chick set up. Leave them there, let the little ones out to free range a little bit, again, so as to explore without being chased.
Do these things for a couple of days, then put them all together and watch. If the chicks can retreat to the safety zone, you are good to go. If there is a single or a couple of birds that are very mean, they go back to the chick place. Let the nicer older birds and the chicks work it out for several days... then try again. If your chicks out number your older birds, it should help.
Good luck,
Mrs K
