My dog tested positive for this in his stool, he has had 2 bouts of diarrehea the past 2 months or so, both needing to be treated with meds from the vet, today his sample came back as positive. My 2 chickens 17 weeks old have no symptoms at all. from what I have read and seen ( poop pics) yuck! they do not have it. My vet has no chicken experience at all. She did say that they might be carriers of it and that is why they do not show symptoms. If so I imagine i would need to treat them for it, so he doesnt get it again. I can get the medicine for him from the vet, but what do I give the chickens? I read corcid? sp and sulmet. Where can I get these and what are the doses and where in southeatern Mass can I get them tested? Also since he has it , that means all the soil in my yard is contaminated with it, what do I do about that?? Thanks for any help in advance.
