I've already dosed my chicks with Sulmet for cocci when they were about 4-5 weeks old. I did it after noticing blood spots in their poop. After medicating, there wasn't any more blood to be found in their poop. But a few weeks later I added a few more chicks to the group, and yesterday noticed a bloody poop. I started again today adding Sulmet to the communal water fount, plan to follow the recommended dose for the next 5 days. What do you think about that?
