My wife and I have bought new chicks to increase our flock and prepare them to lay egg by next spring. I treat them with Cordi and or medicated chick starter. We keep their brooder clean and constantly clean and replace the water and feeder 2 to 3 times daily. Some chicks are pooping blood which I know is not good. One person and the co-op told me to make a oatmeal|corn meal| bran| and powdered milk remedy to help their digestive track. Does anyone have any other advise.
