I woke up 3 days ago and found a limping chicken. She would still get around but would take an occasional rest. She slept outside the coop as she was unable to get to the roosting bar. She did this for two days. I had her on aspirin and would give her electrolytes and yogurt via a syringe (w/o needle). She finally went back in coop and roosted with the girls. The next morning, the chicken next to her remained on the roosting bar. I thought this was rather peculiar. I picked her up and put her on floor. She was completly lethargic! Her movements are seizure like and her eyes are barely opened. She has been like this for 3 days now. I have her on antibiotics and electrolytes. She looks like she is gasping for air. Today, I woke up to another chicken who looks nearly dead She was on the floor of coop. She was completly fine the day before Is this Mareks? or could have my chickens been poisoned? Does Mareks really kill chickens this fast? I am torned!!!
