What's up with the Messy Poopy But? I have this hen and her daughter who have the same issue though mom has it worse by far. I tried apple cider vinegar in their water and I thought it looked better after that but here we are again - this photo was taken today. The skin showing looks very red though you can not see it in the photo (When I go out there they think I am bringing treats so it's hard to get a photo pf the back end). A few weeks back I washed her all off and dusted with DE... I don't know what else to do. Anyone have any ideas? Except for her daughter the others all look fine.
