Sneezing, wobbly, depressed bird. Could this be Marek's?

[pat45159]

I have an approximately 20 week old Brahma cross hen who is sneezing, wobbly, and listless. I have her separated from the rest of the birds, and have been giving her duramycin (Duravet 10) in her water for the past 3 days and Poly-Vi-Sol vitamins. She is eating pretty well, poops look normal, but she's not really getting better. I got her 2 months ago from a breeder who said she was vacinated for Mareks, but he only told me that when I asked if he vacinated. I got 10 hens from him all at the same time, the rest seem fine. The weather was cool here, but it's been 70 for the past week.
I've posted a photo, as I think her eyes look odd - which is one of the signs of Mareks, but seems that chicken's eyes do look a bit odd when they aren't feeling well.
Since there have been so many posts on Marek's recently I am concerned. I am new to chickens, and fortunately have not had any serious illnesses (yet).
Any ideas would be welcomed.
Thanks.

I think it would be best to go through the different respritory diseases (CRD) including Coryza, IB, ILT, MG and even NC (newcastle) first before worrying about Marek's. Unfortunatly many of them are no better than having Marek's. Eye look weird, but other things can cause eye issues and changes in the eyes are just one of the Marek's symptoms, at that I don't think the most common either.s

I lost a vaccinated 13 week old pullet to Marek's. The iris part of her eyes looked kinda gray for a while before she had coordination issues. Those symptoms came on suddenly and there was no sneezing or coughing. I do not know all of the symptoms of Mareks. I also had some pullets who developed sneezing and coughing. I put them on Duramycin 10 for 5 days. On the 5th day is when I could see they were getting better. Just sharing my experiences, I certainly am no expert.

Does your bird show any signs of paralization? (sp) Usually the show signs of legs or wings being paralized. They also do not want to really eat or drink. Hopefully this is not Mareks and hopefully a common cold. Are you able to get VetRX? I suggest putting some VetRX over the nostrils, under eyes, and a drop in the mouth for a few days. See if that helps and it's all natural. I hope your birds feels better soon!! Beth
