Please Help

I have a 4 month old legbar pullet who is ill and I can't figure out what it is. She has been this way for approximately five days. The poor coordination is accompanied by sneezing. This video should explain:

I should add there has not been any nasal or ocular discharge.

Just a few of the many amazing folks that help out

Sorry about your chicken. The lameness in her leg and stumbling brings to mind Mareks disease, but an injury may well be possible. Was she vaccinated for Mareks, and have you ever had any lameness or mysterious deaths in you flock before.
The sneezing might be due to environmental factors such as dust or an allergen, but a respiratory disease might be the cause.

It'd probably be a good idea to share what she eats, was she vaccinated for Mareks, have you brought in any other birds, Hatchery chick? Just a few things that might help the knowledgeable folks here

Edited to say: Oops! I didn't realize someone was already helping out when I posted this. My apologies! Here's hoping for the best outcome with your beautiful pullet. I absolutely adore this breed!

I hate to say this, but I fear it could be Marek's. Is a vet an option?

Thanks. She is not vaccinated. I have had one or two unexplained deaths in the past...never had anything like this. None of the other chickens are showing signs.

Hopefully, we are wrong about Mareks, but here is some reading about Mareks disease:

To diagnose Mareks, having the state poultry lab perform a necropsy and testing after death is the most common way, but a lab, http://www.vetdna.com/ can do a test on blood serum for $20 if you can collect it locally. Here is a link for finding your state poultry vet:

Just in case, have you checked her over really well and felt around for any kind of swelling/heat in her thighs and/or legs?
