I have mareks in my flock (diagnosed via necropsy in october 2014). An 18 month old hen failed to go into the coop at night, found her after dark huddled in the hay under the coop. She had watery eyes and swollen face. I am treating her with vetrx, and boy that stuff is amazing. very fast improvement in the eyes, although the facial swelling remains on the 2nd day. I know this could be another vicious disease, she is isolated and so far none of the flock is showing anything similiar. However, she misses the food when she aims for it. Will be pecking in the air next to the feed dish. Has anyone had a chicken who has the mareks symptom of missing the feed survive? I am willing to nurse her along til she recovers from the respiratory thing but am not able to handfeed her for long. (leave work before dark, return after dark, not much chance to feed her then!). I am trying to decide if I should cull her or if she will improve enough on being able to feed herself .
