I have a Delaware who is almost a year old who has recently started a large collection of poop/mud on her butt. I have a flock of 4 and they are run freely on our property. I noticed some runny dark poops the other day and some that had "clung on" to her butt feathers but didn't worry too much about it as the poops do vary a little form time to time. Today, the collection of gunk on her butt was larger (like a walnut still in its shell) so I started to worry. It doesn't totally look like poop but it's definitely hard and brown. I tried holding her and dunking her back-side in water to loosen up the mass but didn't make much progress. Is this something I should worry about? I read another post about mites but she is totally strong and acts very healthy other than the poop problem. ???? If I do need to do more cleaning does anyone have any tips for it? This is a chicken who will tolerate being held but doesn't like it all that much. She looked terrified when I dunked her butt in the water and soon started struggling to get herself free again. Needless to say, it was about how I imagine it would go if I tried to bathe a cat. Thanks to all for your expertise!
