I posted yesterday about bloody diarrhea. I had 23 bantam chicks, now down to 20. I started them on Sulmet last night around 10:30. I have had 3 die since then and have 7 or 8 now that ar very sick. I am separating the sick and not sick but treating them all with Sulmet. I went to feed store and got medicated feed and probiotics to add to feed. Questions: 1. Do I feed them the medicated feed as well? 2. What else should I do? 3. Is this Cocci or something else? Symptoms: Very bloody diarrhea, "Puffy", no sneezing, or coughing. Some are listless, and standing still with eyes closed.
