ok so i have a weird scenario and would like some second opinions, my horses were having diarrhea so i had a fecal sample done and the vet and the results that were sent back said that they had gotten cocci from my chickens they do share an area so i didn't think anything of it but as i started researching i found that normally chickens die within a week from getting coccidia without treatment i found out 1 week ago and haven't started treatment i haven't had a death in the flock in at least 8 months and none of my ducks or chickens have shown any symptoms besides i saw what looked like a little orange red color tinting their droppings but thats it there all acting perfectly normal. I don't want to treat if thats not what it is but at the same time thats what the fecal test results came with that? any ideas ? P.S. i recently added a pony to my farm last February and he came from a farm with chickens, goats, sheep, other animals and he had diarrhea for about 2 weeks but i figured it was just nerves so I'm wondering if he brought ti with him?
