When one of my chickens had Coccidios, she still had bloody stools for several days after beginning treatment. So, it could be normal. However, may I inquire, what is the Corid dosage that you are using? And is it Corid liquid or Corid powder?
That dosage is correct, so I don't think that is the problem. Maybe the Corid is irritating their digestive tract? I've only ever heard of Sulmet doing that, but I'm sure its not unheard of. Maybe give them some probiotics in their water, if you have/can get them.
Do you know for sure they are drinking the medicated water? Add warm medicated water to feed so it resembles oatmeal, chicks love this and has the added benefit of cocci medication in it. You can increase the dose,if you are still seeing bloody poop. Bloody poop is normally gone in approx. 24 hours. You can increase the dose to 3/4 tsp. You have not been giving any vitamins during cocci treatment,vitamins interfere with the ability of medication to work. You are seeing blood,and not intestinal lining?
The information I found on BYC said 1/2 teaspoon powder per gallon of water. I guess there is some controversy on the topic...
After considerable research by several members on forum,we have found that the 1/2 tsp is for moderate outbreak, 3/4 tsp is for severe outbreak. I will be giving the 3/4 tsp as dosage information from here on. I have also found that going back and looking at forums,when using the powder 1/2 tsp dosage,some chickens are not getting better as fast as they should have been,this tells me that the dose does needs to be increased. There does not appear to be any problems with birds that have been medicated using the 2 tsp liquid dose,they are responding to treatment like they should.
