New hen beat up by older hens...

[hzemag84]

We added 6 new hens to our coop with 2 older hens and they beat up the smallest one. Found her on her side at back of coop, eyes closed and labored breathing. Only visible injuries are few pecks at back of neck. Brought her inside and kept her warm and gave water with ACV and food. After a good nap she woke up and ate and drank and is now standing and pooping and seems fine. I can either out her back in coop and leave older 2 out to free range and let them back in at night and see how it goes OR put her in a smaller coop with a broody mama sitting on eggs... What should I do? pic is how I found her

One of my hens got beat up by another hen. One of her eyes is closed. The swelling has gone down, but she cant see too good with one eye. Is there any way I can open her eye lid without hurting her too much?
