I have a 3.5 year old dutch bantam that is showing clear signs of Mareks Disease. Both her legs are not unusable and she is refraining from eating. I have not had any new additions to my flock and I stay away from other flocks (although 4 neighbors do have chickens and I can only control wildlife but so much). 1. Has anyone had any survivals with Mareks Disease where the chicken was able to go back to living a normal life? 2. Any idea how I could have contracted Mareks considering I keep my coop and run clean, I've had no new additions, I stay away from others and I have netting overhead of my run but some small wild birds do manage to get in at times? 3. How can I protect my flock that has been exposed to the chicken that is showing signs? (The chicken showing signs is inside away from the flock but was outside for much of the beginning signs as I thought she just pulled something in her leg) Any advice or input is greatly appreciated!!
