I had a hen die yesterday from blackhead before I could treat her with metronidazole. I found some in a powder form at a local pet store. I found a dosage for mixing in water of 100g per 200L, so that means about 1893mg in 1 gallon per day for 5 days. That seems like a lot. Is that correct? Also, should I treat the rest of my hens even though they are showing no symptoms? They all free range and have had access to a lot of earth worms recently. I follow a regular deworming program and am planning to deworm with Ivermectin today.
