help!!!

Help! My chicken pop tart started showing weird symptoms today. One of her eyes will not fully open and she is wobbling and unable to walk straight. On top of that she is unable to eat (she tries but then drops it) but is drinking normally I’ve added probiotics and recover 911. I’ve noticed some drooling and also a small bump next to her nose which may be hard to see in the picture.

I want to note that I bought her and her sister through an add on craigslist. After the 30 day separation for my original flock, i finally integrated them and they started showing signs of Coryza which then infected my initial flock. I’ve given them antibiotics for the past seven days to alleviate the symptoms and it helped all of my flock it seems.

***I do not plan on introducing any more chickens or selling my chickens given their sickness and I am not culling them unless they appear to be in extreme pain that I cannot fix.
