I currently have a chicken with what I think is Marek's. I have her isolated. I also have chicks hatching out. Is it a good idea to vaccinate? I have read yes and no. So I'm confused. I was unprepared for this so I will need to order the vaccine. No local farm supply store carries it.
It doesn't prevent them from contracting the disease. It only prevents the tumors from forming. I decided not to.
