I am sure there is an answer to this somewhere here, but I am too distraught to search. This morning I found a pile of seemingly normal looking poop but engulfed with what looks like blood. One chick (17 weeks, but still my chick) did not come when I came to feed, like everybody else does. I even tried to coax with corn on the cob treat, which they all love. She won't budge. They are all 17 weeks, happy and comfortable. Even in this heat. I keep blocks of ice in their water, I have a barrel fan going most of the day, especially at peak hot times, the coop is open air shaded from direct sun in the "open" side of the barn..... I'm sorry if this makes no sense but, Please help me.
