Have you been cleaning the eye and applying eye ointment 2-3 times a day?
The eye still doesn't look cleared up, you may need to give her an antibiotic in addition to the cleanings to see if that helps.  Do keep in mind, if it's due to respiratory illness like Mycoplasma, then she will be a carrier for life.
If she was with the others when the eye started to look bad, then whatever she has the others are already exposed.
I would at least let her with them during the day, when they are isolated they seem to get depressed.
The poop looks pretty good! LOL  The older they get, the bigger the poops get.
Well.   Looks like abx are sold out.  You may have to get on an email or waiting list.  If you have a vet that can give you a script that would be good too.
To treat symptoms of Mycoplasma, you can use Tylosin (Tylan), Tetra/Doxy/Oxy "cyclines" and Tiamulin (Denagard).
