Both of your girls are absolutely beautiful. For me, the animals around me make life more colorful, and by far more enjoyable, and even worth the heartache that sometimes comes with these creatures that need our stewardship. Know that all of us are here with you every step of the way to lend guidance, advice, to be your cheerleaders, and when the time comes, a shoulder to cry on.
Don't give up! Everything will work out, and I hope that you continue to feel like those beautiful girls out there brighten your day, and just by their presence were worth the effort.
My first easter egger, Waffle, was the lowest bird in the pecking order. She was timid, standoffish, and got picked on alot. She lost all of her flock mates to a predator over the period of a week. I couldn't let her live alone, so I regrouped, built a better house for her, and got her new flock mates. As everyone grew, Waffle became the sweetest bird, so full of personality, and so loving. She also took a new place in the pecking order with her new flock. Waffle became the ultimate matriarch. Even superior to the roosters, only allowing one to mate her, and only on her terms (think wine and dine...the whole nine yards. She made him work for his prize!).
I really think that adding new girls will help your flock dynamic.
I hope everything turns out, and soon!
edit: by the way, bantams might be an okay chice...they may be less intimidating for your Ginger girl...even if you only get one bantam?
