What diseases look like Marek’s but aren’t?

[CochinFancy]

Hello all,

Which diseases look like Marek’s but aren’t? I have a chicken that can’t walk and is uncoordinated but all that comes up when I search that is Marek’s. None of the other symptoms match. They also don’t match to New Castles.

Maybe something that is genetic or not passed by a virus?

How old is the chicken? Have they molted this year. Is it drinking fluids and eating? Vitamin deficiencies, moldy feed, a toxin or poisonous plant, lead poisoning, and dehydration can mimic Mareks symptoms. Here is a good article with info on those other things:

She ended up dying. I thought it was a vitamin deficiency and treated her for it. She perked up some and then died. It still might have been, I choose to treat it orally instead of inject because I was afraid to. No idea the cause, still don’t think it was mereks.
