@Aunt Angus Most of us do not have vets who will see or who have a lot of knowledge of chickens. Some near large vet colleges can get their chickens tested. C. Perfringens is in the soil everywhere, but it can be a cause of enteritis. Most chickens with it usually have had coccidiosis prior to having enteritis. Let us know how your experience with the mail in fecal test goes. I haven’t heard a lot of people saying if they showed worms and what kinds. It would be good to know if they are fairly accurate or not.
I always ask my dog vet if they have a vet who will see chickens if I need to get help. They have said they will do a fecal float, but I have yet to take them up on it. The ones on my dogs cost about $37 now, so the mail in test would be less expensive.
