I have 2 baby chicks that are both in seperate brooders with other chicks. I have noticed blood in their poop along with being lethargic, pulled in heads and drooping wings. They are on manna pro medicated feed which I thought was to prevent cocci. From all I'm reading these are the symptoms. I've read on BYC about sulmet and corid. Can these be given while on medicated food, and is there any other way to treat this? Any help would be appreciated befor I lose these babies.
