I need help!

They can be carriers from just being exposed, and may not show symptoms. If you are very lucky, they may not have been exposed. As you will read in the links, they can show symptoms of MG within 3-10 days of exposure. Coryza may take only 2-3 days. Both organisms will only live in the environment for 2-3 days. I hope that sending them back solves the problem.

Aren't bubbly watery eyes a symptom of MG? My chickens do not have that. I hope it's all over with.

Foamy eyes are a sign of MG, but that is not always present. Foam can also occur when the eye is swollen from an injury or insect bite. One of my hens with facial feathers will sometimes get foam in her eyes on very frigid mornings in winter from a tear duct issue.
I hope that your hens are well on their way to recovery.
