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?

So overnight after she calmed down and slept her breathing this morning, while still not the best, is much better.

Here's something to add: when I turned the light on in the room she is in, she was breathing through an open beak, but no where near as bad as last night. Then she sneezed and she stopped breathing with an open beak.

To add, she spends most of her free range time alone in the wooded area. Could this be something environmental, from something in the wooded area?

Thoughts?

I found an old dog crate my son used to have, probably one of the biggest you can find (his dog weighs 100 lbs). I put it back together and in the corner of her run because I know she didn't like being left alone in a bathroom in a collapsible pet playpen! She is breathing OK and she is drinking though I haven't seen her eat much. Alone in the crate should give her a chance to eat without her flock mates pestering her.

She may be a loner or low in pecking order. The crate may help her get plenty to eat without bullying, while still seeing the flock. Does the rooster chase and pick on others? You could possibly separate him if needed.
