I asked on a different thread, but wanted to start a new thread to respect the other poster.
I have 7 chicks that hatched 6-7 days ago. My wyandotte is being a fantastic broody, but our first attempt at integration didn't go very well. I only have 2 other hens: An Ameraucana (who was the lowest in pecking order) and an Easter/Olive Egger who is usually pretty laid back but not bottom of pecking order. I will attach photos of the setup as suggested by @aart

Outside view looking into the run. The main coop is in background. This is all a dog kennel which we framed up, has roof, etc. Bottom 2 feet is hardware cloth with hardware cloth bent and buried in ground. I don't think they can escape from the big run. The broody box/run is in the foreground. It has a box in back which Rosemary used to incubate and hatch the eggs. So, the other 2 have seen/heard the chicks since day 1. When I let them out earlier today, Ginger (Ameraucana) was very aggressive to the chicks. I intervened after she pecked one of the chicks, but Rosemary didn't really defend them. She tried to position herself in between, but she wasn't aggressive at all like I had anticipated. I ended up locking Ginger/Olive in the main coop to allow Rosemary and her babies to check out the run. The chicks have a hiding place, but only on this side of the coop. They get in between the broody box/run and the outer fence. The other hens cannot fit in the space, but they don't have a central hiding spot or "Panic room".
Here's another pic from inside the run:

If I have a panic room, Rosemary wouldn't be able to fit in it.
I tried again later with just Olive in the run. She didn't really seem to notice them much at first, but after a few minutes of scratching she chased one and pecked it. Rosemary didn't really do much. I guess my main issue is she isn't aggressively protecting them. She never pecked me during incubation or hatching, etc. Suggestions?
Here's a chick photo just for fun:
