One of my 4 week old (3 at the time) chicks was showing symptoms of Cocci, droopy wings and very bloody poop. I started treatment on the whole batch of chicks with Sulmet, and I went through the full 6 day dosage schedule following the directions on the bottle. I also started them on medicated feed and gave them some plain yogurt every day, along with adding powdered milk to their feed. Everything seemed to clear up, and the symptoms went away. It's been 4 days since they've been off the Sulmet, and I think I saw a tiny bit of blood in a few of the droppings when I went out to check on them this evening, but it was getting dark, so I'm hoping it was just too dark for me to see clearly, and I was just being paranoid. None of the chicks seemed to be acting sick, so I just turned their shavings, put fresh shavings in their sleeping cage, and will check on them again before I go to work in the morning. However, if the Cocci is coming back for another round, how soon can I re-dose with the Sulmet, and would I go through the whole dosing schedule from the beginning again? I actually found some Corid at the feed store over the weekend, but the medicated feed I'm giving them now says not to use anything else with Amprollium while using the feed, so I guess that just leaves me with the Sulmet.
