Two birds with eye issues - Coryza?

[Eggcessive]

I would guess that she has mycoplasma (MG) which causes conjunctivitis and sinus infection. Here is some reading about it:

Culture came back as avibacterium gallinarum. I’m sure he said that, not paragallinarum. Associated with or causing Infectious coryza. They have done a week of antibiotics, now that culture has come back he is switching their antibiotics to one that was tested against the bacteria (the initial one wasn’t). The Pekin’s eyes are both inflamed, the original one has started to get better the other looks the same.

I think two of four were vaccinated for coryza, the pekin I’m guessing wasn’t. It still is mild considering. Someone saw a photo of her at 6 weeks and thought she looked sickly - I think she might have been sick or infected when I bought her. First time chicken owner I had no idea. $500aud on vet bills and medicine later…

Obviously this will be a closed flock. I will not be culling and had no plans to add more. Just very disappointed as this is my first foray into chickens.
