Ok Hopefully I am getting this straight? lol Indeed I am very tired and wearing out... Is the API General Cure the same thing as the Fish Zole?? The General Cure has metronidazole in it, but from what I can tell there are other ingredients in it too. I will call tomorrow and see if the vet that did the float will get me some Flagyl and if not then I can order the Fish Zole online or pick up the General Cure. Which ever is better? Yes, I did read on one website that chickens do not always show every symptom of blackhead. But, it is very common with this type of worm. They can be introduced to the cecal worm through earthworms, too. Which does not surprise me if she got a hold of an earthworm that was a carrier of the cecal worm itself. I might have narrowed it down tonight... Michael Apple did give me advise about the Flagyl and treatment process; which I am grateful for. Eggcessive, you both seem to be on the same page so I will go with this information. Michael said to treat with safeguard then wait a couple days and if she is not improving to do the Flagyl. My only question now is should I continue with the Penicillin for another 3 days? then give her a break with vitamins, minerals and probios then if she is not better do the Flagyl/Fish Zole? I think this is what he suggested but I was a little confused probably because I am tired... LOL
