can Coccidiosis be spread to other birds that have been and are still being fed medicated food? I have a chick that I think may have it, the only symptoms she displays, is bloody poo. it's happened a few times now in the last week. we just got this group last week, at first, I thought it was just a shedding of the intestinal walls, but it seems too frequent for that. I think we found the sick one, she had blood around her vent. She has NO other symptoms though. When we got these they were raised with momma & daddy, and free ranged. I don't know what to do?
