I believe my 2 month old chicks have Coccidosis because of the sudden onset of very bloody stools I found this morning. On another thread I was advised to use Corid, which I cannot get until Tuesday, so I have begun treatment with Sulmet until I can get the Corid. But never having dealt with this before, I have some questions: 1. The chicks run loose in a large fenced in yard that my Chihuahua was playing in a few days ago (I'm teaching her not to chase them) and so I would like to know if she can catch this. If so, how long until I would see symptoms? She is utd on shots and takes Interceptor for heartworms. 2. Just how contagious is this? The chicks get out of the fence once in a while and the other birds also range in that area, will they catch it? 3. Is it easily transmitted by my walking into the other birds pens? 4. Since cocci are parasites, should I also worm the chicks? 5. Must the coop/pen be limed or something to keep them from reinfecting themselves?
