I have a young hen who recently had what I thought was sour crop. I had made a bunch of phone calls to see if I could find a vet in my area who deals with chickens. Eventually I found one. I told her all of my chickens symptoms and she told me that it sounded like Mareks to her. Her symptoms are as follows: Bloated and enlarged crop that seems to be liquid filled and hot to touch It doesn't empty out from day to day That is all, she really has NO other symptoms. I was sure that it was sour crop and now this vet has me freaking out a bit!! If it is Mareks, I know that my other chickens are probably doomed. My other chickens seem fine so far. She didn't actually come out to look at my chicken and I don't know if it really sounds like she knows what she's doing anyway!! She said it's outlook was grim and the chance for survival are slim. Which if it is Mareks, I know that!! If for some crazy reason it would be Mareks, is it transmittable to humans?
