What could be causing my chicken to poop like this?

[AxelLovesChickens]

I recently got a couple chickens. One of them (Lakenvelder) was about 8 weeks old when I got her. She’s about 10 weeks old now. She’s been doing these yellowish, creamy poops ever since I got her 18 days ago. Today I noticed (for the first time) blood in the sample pictured here. I’ve been treating her with Corid for a little over a week in case it was coccidiosis with no signs of improvement. Other than the poop, I think she’s acting perfectly fine. She seems active, social, and seems to have a perfectly fine appetite.

Any idea what could be wrong? I’d really appreciate any advice.

Where did you get her from and what are you feeding?

I got her from someone local to my area with a large flock of seemingly healthy birds.
I’m currently feeding a ~50/50 mix of Dumor 20% starter/grower crumbles and Healthy Harvest medicated starter/grower crumbles

Don't quote me on this, but I'm pretty sure that medicated feed can override the effects of Corid. @Wyorp Rock?

If you have been giving the correct dosing of Corid for 7 days without results, then I'd switch to Endocox (Toltrazuril).

Liquid Corid dose is 2tsp or Powdered Corid Dose is 1 1/2tsp per gallon of water given for 5-7 days as the only source of drinking water.
Do not add any extra vitamins/electrolytes that contain B1(Thiamine) to food or water during the course of treatment.


In the U.S. medicated feed contains a minute amount of Amprolium/Amprol which is the same ingredient in the name Brand Corid, so no, the medicated feed would not override Corid.

My bad, thank you for verifying @Wyorp Rock
