I don't know what's wrong

[maneuvers]

Maneuvers, how is your chick doing?  Many people on BYC have reported Mareks symptoms in chicks who were supposedly vaccinated.  It takes 2 weeks or more for chicks to develop immunity after vaccination, which means if there has ever been a chicken on the property with Mareks (like on an old farm) they could get exposed before immune.  I live on a very old farm myself, and I have always worried about Mareks.  My first hatchery chicks were vaccinated, but the ones I have hatched with broodies or an incubator have not.  Some say that Mareks can last 7 years in the environment, but I suppose it could last much longer.  Do you have any old lead paint on buildings around your coop?

No lead paint possible. She is very lively eating and drinking but stays in her back. Her stools are now green blobs. I'm worried that I may have to put her down but she doesn't seem in pain at all. Going to give her a fighting chance.
