Actually Coupe, her birds have already been exposed if it is in fact Marek's. Closing the barn door now is an effort in futility if you ask me. Also, since these birds were vaccinated for Marek's, there isn't any more risk for them now than there was when it first happened. If they are going to 'get it' believe me they already have it.I still wouldnt put her near other chickens...i still think its mareks. Some birds can live awhile with mareks.
When I first read this thread I had misgivings on whether or not it was Marek's. Symptoms didn't match up with what I have seen with this disease. Very rarely will a bird go down overnight with no forewarning symptoms. It just doesn't happen that way, there are always hints to tell you what's coming if you know what to look for. Annie44 didn't mention any of them in her first post. It wasn't until I saw the picture that I 'knew' it was Marek's. Anyone who's dealt with this knows that vaccination is no guarantee against a mutated form of it coming to visit. In fact in some instances, the vaccination actually makes it worse. This is why I went off on her when I saw the picture. All I could think of is where she is and what hit on the East Coast last year. I was quite frankly, scared and saddened that even through the harsh winter we just went through, it could still be showing up a virulent as it had last year. Right now I am very happily eating my words. Am I convinced it's not Marek's? To be honest...no and that is another reason I have asked Annie44 to please post everything she can about the findings and medications. Something is different here...very different and I for one would really like to understand it. I have never had a bird come back from full roadrunner position. With a mild outbreak and some paralysis, oh yeah, they can come back and 'thrive' as much as they can. I now have Marek's survivors over a year old who have done this and other's do as well. After a year of age most birds have been exposed to it anyways, whether vaccinated or not and are able to build resistance.
