I thought I would keep you all informed, since you've helped me already. I contacted my vet, who gave me a number, anyway--that was a long story. Ended w/3 hours on the phone w/ DATCP. Finally called ext agent. She got back to me w/2 testing sites for me to contact. I will contact them tomorrow. I had to turn the feed in b4 I was informed of the info. I did keep a sandwich baggy full of feed. I don't appreciate the person telling me they already know it's cocci. I thoroughly disagree. I am not an idiot when it comes to raising animals. No, I don't have a thousand acre farm. However, I have raised chickens, pigs and turkeys for several years. This is not normal. When they are perfectly healthy til one bag of feed is provided and then they stop eating and die, something is wrong!!!
