I wormed and treated my flock with corid after a couple hen deaths and several poopy butts. One hen has been lethargic since I started treatment. She was pale and had diarrhea. She doesn’t eat or drink much and just stands around. I separated her and gave her electrolytes and vitamins. Her stool firmed up and she is gaining some color back. Still not eating or drinking much, and just stands there. Ideas? Crop is not hard, she is not egg bound (she has egg peritonitis and I drain her monthly).
