I noticed a couple of weeks ago that one of my Buff Orffingtons had a dirty butt area ... instead of the fluffy downy type you normally see. Last night she would not go back in the coop and when I picked her up I noticed something kinda strange around the vent area. There was alot of poop stuff on the feathers and something coming out of the vent. I took a pic but it is not all that clear. There is a small finger size something that seems to be coming out of the vent. I kept her inside last night and was able to clear off somemore of the frozen poop this morning but I am unsure what to do now. She seems active and alert - she eats and drinks. If anyone has any suggestions of what I am dealing with here I would really appreciate it. Thanks.
