I too, think you are passed the worse, I would not separate anyone, or they will have to work it out again!
I did have her separated within the run. They could see/hear her. I'm not completely comfortable with just leaving them mixed at this time, because I'm not home during the day to check on the chicks. I let them out several times yesterday. She's been sticking closer to home base, BUT she's been more puffed up and aggressive with the other two. She has "hen-pecked" Olive several times and poor Olive just sits there with her head down in a submissive position. That's good for the chicks. Ginger has mostly avoided her. I plan to let them out every evening this week when I'm home and this weekend make a more permanent move. My plan is to put the broody box/run up on 2x4's or Cinder Blocks to elevate it high enough for the chicks to get under for a panic room. Rosemary won't be able to get in during the day, but I'll open it back up in the evening so they can sleep in the nest. That way the chicks can move in/out of the broody box to be with Rosemary.
Thanks so much for all of the suggestions! If I were home during the day, I would definitely see how they handle it for a full day, but I don't want to come home to abused chicks.
