So I have been fighting a losing battle against coccidia. Keep baby chicks inside completely separated from rest of flock. However, at 2 to 2 1/2 month of age when I move them to an outside coop still separated from adults, they end up getting coccidia and I ultimately lose several even after catching some with symptoms and starting treatment with corid right away. I have had some die on me even being on medicated feed before even going outside. What am I doing wrong? I keep everything as clean as possible, change the water and feed daily and wash my hands when handling the chicks
