I have begun integrating my polish pullets into my mixed flock of adults. They don't get bullied anymore than the non-polish pullets that are also integrating with them. Maybe trim a few of the feathers around her eyes if she has trouble seeing. Doing so has worked wonders for my Buff Laced Polish, who used to frantically run around and bump into things whenever another bird bothered her. The harder it is to see other birds coming and the more sporadically they move the more likely it is for them to be picked on.
Also I agree with what @CaliforniaMountainChicks said. Giving the birds things for entertainment will help.
So I think they’ll be fine outside at 4 1/2 - 5 1/2 wks old. We’ve just got one or two more things to tidy up and then they can safely go outside into the coop. I’ll miss them once they’re outside. I told my husband I’ll be moving out there with them. #crazychickenlady Thanks for the tips. 
Are Polish sensitive to heat? She doesn’t seem affected at all though
I hatched my 6 beautiful Tolbunt Polish and a bunch of other chicks—d’Uccles, d’Anvers, Olandsk Dwarfs, Brahmas, and a bunch of barnyard mixes…but I’ve only lost my Polish and all after 10 weeks. They all presented with the same symptoms so I knew it couldn’t be an illness since no other chicks but the Polish have shown any signs of illness. They were all fine, then within a week they were practically skin and bones, had odd skin lesions, and lost the ability to walk. They would give up trying to eat and die from organ failures. NO other illness signs, no lack of appetite or drinking…so when my FOURTH Polish Axel started wobbly walking I brought him in and started him on Tylan injections in case it was an illness even if I didn’t think so, and then began a treatment of vitamin E and B complex every other day. He has gotten iodine soakings for the skin scabs, baths to keep him clean, and food and water and his vitamins for 3 weeks now. I was sure I would lose him and planned (still will if things go backwards) to send him for necropsy. However, I noticed about a week ago that his right wing was moving a bit and he had started vocalizing more instead of acting quiet and sickly…and today, he almost stood up on his own and walked a step or two!
