ILT spreading?

[Chickenkeeper23]

last week one of my three month old chicks overnight deteriorated and was seprated from the flock, she was coughing mucus/ blood, and had off and on trouble breathing and died several hours after I originally found her.

Today two of the chicks brood mates have eye discharge in the form of bubbles and there eyes are slightly swollen ( barely any swelling but I know there baseline) as well as very minimal nose discharge.

We are not sure what the first chick (squiggle)passed away from but I want to make sure it’s not spreading . Squiggle didn’t have any eye discharge and The day she passed away I deep cleaned the coop, roosts, and walls as well as I could.

Please any advice is appreciated!!!!!
Is this probably something else?

I can't advise you on how to treat this. But if another bird dies, send the body in for a necropsy. Keep the body cold, but don't freeze it.
This site has a list of places that will do a necropsy, by state.

They will be able to tell you what killed your chicken.

The eye bubbles and wheezing sound like Mycoplasma infection.

There are a lot of threads that give descriptions and treatment options.

Use the search bar and type in Mycoplasma.

There are so may I couldn't pick one to link.
I've never dealt with it so no first hand experience to offer.
