I went out this evening to do a final check up on my crew,and found some feces with blood in the stool.After looking over the chickens I noticed that my one hen has a protrusion on her vent that is beet red in color,almost like a big hemmroid. She is missing feathers from around the vent area. I have just had these chickens for four days. I was reading about worms and had wondered if that was what may be making the red area and Im not sure who is doing the bloody feces although I looked and did not see worms. She is six months old as are the other 2 hens and have laid no eggs.I have them on DE as well as in the dust box and have ordered Piperline and Ivermectin online. What could this be?
