Limping, sneezing, wet tail feathers?

[Barredhen]

Thanks again! Read one of those, reading the other now.

Here is a video of her now, she goes between days like this where there is only an occasional off step or leg holding, and somewhere between the first video and this, but never as bad as she was!
Is there a test to confirm this was Mareks without killing the bird in question?

I See the answer to my question re testing in a link you posted, thanks!

They look very good now. Perhaps it was just an injury or vitamin deficiency. I don’t think Mareks symptoms just go away that often. If you could contact a lab that does Mareks testing, and then got a vet locally to draw some blood in the way they need, you could send that off for testing. Blood tests for Mareks are not as accurate as testing done on feather shafts or tumor tissue, collected after death, so there can be a chance of a false negative test.

I was just doing some reading about another disease called peripheral neuropathy in chickens that can look like Mareks, but it is not the same. Interesting subject.

I did give her 1/2 cc B complex inject by mouth a few times and added a vitamin to their water. Like I said, today (this video) is a really good day for her, and she can, if startled, or on a "bad day", look somewhere half way between the two videos I posted.
We had 6 chicks to begin with, one died the night of, two died before I realized I needed to treat for coccidia and this chicken with the leg symptoms nearly died from coccidia but recovered. Now we have just these 3. The other two show NO symptoms of Marek's and I know they can "not" show symptoms, but have, but I kind of think in my uneducated opinion that if it was Marek's another bird of the 3 would have symptoms, or this bird wouldn't just up and look a little better. Possibly hopeful wishing... shes never been sick like dieing, shes just walking funny on the one leg or holding it up!

I'll look into getting a blood test. I'd be curious.
