I have 6-1 year old hens. all seem fine but 1 ( a buff orpington) has diarrhea caked in her tail feathers. the vent is clear of any dried poop and she seems to be healthy. Very hearty appetite, but always has had. clean water, 20x30 outside pen. I have tried the key wrod search, but seems that most questions are about chicks. Thanks for any help.
