Coccocidiosis is probably already in your chicks intestine. It is transmitted by poop, clothing broody hen even on your shoes. It only becomes a problem when there is an overload. Amprolium is a thiamine blocker, not an antibiotic or wormer. Cocci thrives in warm moist environments. Symptoms vary, but usually lethargy and standing with wings down , away from the flock are early signs. I have only experienced one outbreak, and since then am ever vigilant. I lost a few hens quite suddenly and without any real warning, before I cottoned on to what was going on. Don't wait to see blood in the poop, cause it isn't always present.
