From what I have been reading, it seems coccidia is species specific, but I want to double check on this. We have 4 goats, and it is general knowledge that the adults almost always have coccidia in their stools, just don't get sick like the young ones do. Ours were sick with it right after they came last spring, we treated them, and they have been fine since. The birds will be sharing a barn and pasture with the goats, and I just want to be sure they aren't going to be running a huge risk of getting coccidia. I will be feeding organic, no-medicated feed, so I am trying to be vigilant about what theya re exposed to.
