    Last week I started treating my chicks for Cocci based on the symptoms and advice from more experienced chicken owners on BYC.

    I bought Corid. There was only one kind at Tractor Supply, so it didn't occur to me to verify that it was safe for chickens. It actually says bovine on the package. Then I read on a thread about someone getting Corid from a vet that was specifically made for chicks and hens. Am I hurting my girls by giving them the other? I mix 1 1/2 tsp of powder per gallon.

    I hadn't treated my big girls since the chicks are in a separate pen. Then yesterday I noticed a couple of them acting "off" so I decided to treat them, too. I lost one of my bigger girls this morning. The other two looked pretty out of it this morning and I figured it was only a matter of time. But when I came home just now, they were both up and around. Not exactly energetic, but I have hope.

    My 2 hens that are actually laying, are showing no symptoms, but they are drinking the treated water. Are their eggs safe to eat? Should I toss them and wait until they're off the medicine?

    My beautiful rooster is one of my sickies. His comb is kind of wonky. Flopped over and sort of turning purple. Is this a normal part of the sickness?

    Is there a way for me (without digging up a body and taking it to a vet) to know for sure that it's Cocci I'm dealing with? I'd hate to lose any more if I take too long figuring things out.


    Not making any noise

    No energy

    Roo was holding his wings out funny on the perch

    One of them has blood in his poo. Could be more than one. Not sure.

    The one that died was having problems with balance/jumping on the stump.

    Right before she died she couldn't stand up. Not sure if it was lack of energy or balance. She just laid there not moving even when we nudged her.

    Most people use the cattle version of Corid, like you are doing. So, I think that its perfectly fine for you to be using it. I think that you can eat the eggs while giving Corid, as it isn't like an antibiotic (its just a thiamine inhibitor). It sounds like you could have several diseases going on in your flock. Have they been wormed recently? What are their crops like (are they hard, which might indicate impacted crops, or balloon shaped and squishy, which could be sour crop)? The rooster's comb turning purple could be due to a heart problem. Cold weather or hot weather can also cause changes in comb color.

    The Corid sold in the US is labeled for cattle but is safe to use on chickens. FWIW, I called the mfg. of Corid and Amprol and was told that the dose for poultry is ~4.5 grams which works out to something between 1.5 and 1.75 teaspoons per gallon. There only difference between Corid for cattle and Corid for chickens is that cattle get 3/4 teaspoon per gallon, not 1.5. I know it doesn't make sense, but chickens do get higher doses of medications than other animals.

    Now, about your birds... have you ever de-wormed them? Have you dusted them for mites and lice? If so, when and with what?

    You could take a stool sample to a vet and maybe you could dig up your hen and send her for necropsy.
