Protective broody

[Vickischics]

On July 4th a polish broody hatched 3 chicks. She remains very protective and mean to one particular hen(her mama). She will not permit the older polish hen to leave the coop. She remains relentless with her to the point, I have to keep food and water inside the coop. The other flock mates go inside to visit and sit with her throughout the day. But, she will never come out nor is she permitted to roost at night and sleeps on the floor.
Should I separate the mean Broody to break her protective nature and meaness?
The chicks have been raised with the flock since hatching. I believe the chicks are old enough and none of the flock is aggressive.(except broody bitch).
What are your thoughts.

They are 8 weeks and have intregrated very well since hatching. The 3 other Hens have been excepting.
So, what do you think @sourland?
Can I or should I separate her or let it be for a few more weeks?
I just hate my beloved Becky Polish girl being kept inside the coop alone all day in this heat.
I value your thoughts. Thank you.
