Today I noticed one of my barred rocks had the "Watery eye" and some "White foam" in the corner of her eye. I immidetly removed her from the rest of the flock. She must have developed this over night...with the little exposure to the rest of my flock, do you suspect them to be infected as well? I plan on treating with LA 200 or Neomycin. Should I treat the other chickens that show no sign of the CRD? Do i need to some how clean the inside of my coop where she was roosted?
