I noticed tonight while feeding my hens that one just didnt look right to me. The others were happily eating some BOS, and she had no interest in them. Upon closer inspection I saw that she has a messy, sticky looking butt, but it doesnt look like poo really, its looks sort of light colored and slimy. I watched her for awhile and she is just standing there with her tail kind of drooped downward, Then every once in awhile, she will bend her head back underneath her breast to the back end area and kinda pick at it. She is a young hen, she will be 2 yrs old late fall. They were all dewormed maybe 2 months ago. I hope somebody can help me figure out what is wrong with her so I can help her feel better asap. Thanks guys.
