I ordered 4 red stars from McMurray, and they are the sweetest and appear very healthy. <3 Today, I noticed some blood in their stool. Or atleast one. The four red stars are at one end of the roost, and the original 4 I had are at the other, so I know it must be one of the hatchery girls. Anyhow...now...I have seen the intestinal shed thing that can be kinda red-orange, but this was definitely blood. I went on and treated them with Corid, but I am puzzled-they are vaccinated against cocci. So, could it be something else? They are acting fine, and only the hatchery birds have the gooey poop with blood in it... Any ideas?
