Abandoned hen with eye condition

[Little Hen 1972]

My daughter recently bought me 4 hens that had been abandoned in her neighborhood. They been fending for themselves for about 6 months now. My daughter was afraid they wouldn't make it through the winter and bought them to me. I had them quarantined for a month. Three of the four hens were sick and had issues. Those three have healed and my last hen, Her name is Earnestine has recovered from yeast infection and she had little plant spikes on her face that I pulled out and that healed too. But she has had an ongoing eye infection in one eye that I at one point managed to clear up. I had put her in with the flock and she got a yeast infection again, probably from stress from a new environment with many other chickens and the eye infection is back. She's back in quarantine again with hens that are molting and she's once again recovered from the yeast infection but I have no clue on how to treat the eye. I treated her for a month when I first got her on oral antibiotics and eye antibiotic (terramyacin). I washed her eye out with eye wash solution. Her water has electrolytes and I put in herbs to boost her immune system. I was looking into scaly mites but I don't think so. Her eye sometimes has bubbles and the liquid Tears? Do chicken's have tear ducts??? falls on her face and covers the eye area white. I have included a picture. Anybody have an idea??

Not sure what the bubbling of the eye actually is, but my friend had a silkie with the same bubbling eye issue.
Not too serious, she just wiped it every so often with a damp paper towel.

I am afraid it might be a mycoplasma gallisepticum infection. Am I able to vaccinate my flock from mycoplasma at any age> That's question #2.

The hen is actually very healthy and happy besides her eye drainage issues.

The foamy eye may well be mycoplasma (MG,) a chronic respiratory disease. Symptoms may occur after a move or other stress. She might have been in a flock where she was exposed. I would treat her with one of the antibiotics used for MG. Those include Tylosin powder in her water, Denagard or TiaGard, oxytetracycline or Doxycycline. You may get Tylosin within a week here:

I would continue to clean her eye with saline or eye wash. MG can be common in some backyard flocks, and most people close their flocks to control the spread. You canntry to get her tested while she is having symptoms to get a diagnosis. Here is some reading about MG:
