What I believes to be wry neck on my favorite chicken I now believe to be mareks, but honesty I need some other people's experience. I really don't want to put her down if it's something treatable so I just need some help here. Her symptoms are the inability to use her good leg, but she can still move it and scoot about, she eats and drinks fine, but tonight I noticed what looks to be a tumor on her neck just below the beak. It's about the size of a mushy goofball and slightly bloody so honestly I don't know anymore. In really bad with animal sickness and in kind of freaking out. I'm currently logging on to my computer so Ivan upload the picture I have.
