Hello Everyone, I have had chickens for a long time now and I have never really had anything like this happen. I have a hen who is about 2 years old now and she has had chronic diarrhea her whole life. I bought her and 2 other Buff Orpingtons from a feed store...the chicks came from McMurray. She does not act sick, she acts completely normal to be honest. She just has a really messy butt and chronic diarrhea. Does anyone have any suggestions as to what I need to do? She eats very well..she is a BIG hen, and acts normal other than the diarrhea. All of the other chickens are fine and have no issues.
