Marek's or something else?

I believe one of my flocks has Marek's because of many signs and a necroscopy of one dead pullet (no PCR though).

Here is that thread:

Now I have another chicken from another flock that is showing...something.

And she too is a Speckled Sussex, like the flock that appears to have the virus.

Two days ago I noticed she was hanging out more in the woods than usual. Sleeping alot, but could move and fly as well as ever. She even flew up to my shoulder several times that day and yesterday (the only chicken I allow to do this). But later in the day, I noticed she has a slight raspy sound to her breathing. Not all of the time, but it was there.

Yesterday, much of the same.

Today she took two turns for the worse. She got chased by one rooster and it stressed her and it took a good 5 minutes to stop gasping for air. Then later in the day, another chase, and she's been breathing hard ever since.

No nasal discharge, nothing in the eyes, just shortness of breathe at this time. Her eyes are now hazel but I can't honestly say they were not that way already. I know SSes are not supposed to have that color but she was hatched from an Ebay egg...

She has been sneezing a little, but not alot.

Her comb and wattles are still the same color. She stopped laying eggs a day or so ago. Even at the worst of her breathing tonight, her comb has remained the same color.

Does this sound like possible Marek's, or something else?

She is now isolated. I rubbed VetRx on her beak, comb, wattles, and under her wing. I've ordered Tylosin from Jedd's but that will be a long wait.

Her feces have been green sometimes and "normal" others, but she spends most of the day outside free ranging and eating leaves, grass, etc.

I tried to get her to drink earlier but nothing. I didn't want to hold her beak into the water too long so she didn't aspirate.

Opinions?
