Once a year, I test a composite stool of my hens at the vet's office. Will that test cover everything that chicken's might have? I didn't know if there was something funky about chickens that would require a stool test beyond what the vet normally does for other animals. I just feel that this makes more sense than subjecting a flock of chickens to heavy-duty dewormers, if we're not completely sure they're infected. Thanks.
