Please don’t cull!
Every animal has a chance!
Imagine if you had a dieses and you were not allowed to make the choice to live.
How would you feel?
Please read this and reconsider culling that precious life..

And if you do choose to keep her life please let me know too!
Let's learn a bit more here.
You absolutely cannot equate human disease with chicken disease. If I get a cold or the flu, I am not contagious the rest of my life, able to infect others even when I am well again. And I
am well again....chickens are not. They are carriers, Typhoid Marys, able to infect others even when they are asymptomatic!
They are not cured.
Telling people to keep carrier birds in their flocks and act like they had a head cold is doing them a disservice. Most chicken diseases are like herpes viruses or HIV...they are not curable. They only become asymptomatic (seem recovered). The disease stays with them.
Antibiotics do not cure these avian diseases! You MUST learn this fact. It's a harsh reality of chicken-keeping for anyone, but you absolutely cannot wish it away. You sound young, but what you will be doing if you keep sick birds, and make no mistake, they are sick, and you have the mistaken idea that they have recovered, is that you will be responsible for spreading disease to others, especially if you sell or give away any birds and don't inform the new owner that these birds are disease carriers.
Some make the decision to keep and close an infected flock, which means no new birds can come into the flock and none can leave the property, but you also have to use precaution handling them so you don't spread the disease off your property while your birds in a relapsed state. That isn't an easy way to live, very limiting.
It's thinking like this, that you cannot euthanize a chicken for disease, that brings the government down on backyard flocks - don't live in LaLa Land, they
do come and kill flocks for certain reportable diseases! You will have no choice if they find out your birds have something like ILT (Infectious Laryngotracheitis).
Giving Tylan does not cure MG or any other carrier disease, no matter how often you give it.
ALL THAT SAID, simple bubbles in the eyes doesn't always mean MG. It can be a bacterial sinus infection, but that would be
less likely than MG, especially if it's glue-like. It's hard to know without testing.
