Mycoplasma?

Suspecting my hen has an infection. The bubbles in the eye make me think mycoplasma gallisepticum. I’m lucky to have an avian vet in my area, but can’t reach them until Monday. Is there anything I can do for her in the meantime?

My understanding is that MG is an airborne threat. Should I operate under the assumption that my whole flock (6) is affected even though I currently only have 1 bird who is symptomatic?
