Coccidiosis is caused by Coccidia — a protozoan parasite that infects the intestinal tract of chickens. With a typical life cycle of 1 week, it’s often just treated as such (for 1 week); however, many people find that it comes back again shortly thereafter — and that’s because they don’t treat it for long enough. Chicken health is an important topic, and understanding not only how Coccidiosis presents itself in your flock, but also how it’s spread (through fecal matter) and what the ramifications are of treating it — especially if you’re collecting eggs to eat!
