I have four chickens (two Easter Eggers and two Barred Rocks) that are less than a year old (started laying in June). One of my Barreds has been having problems with poopy back feathers. The others seem fine, and I do think perhaps the stool might have been from too much fruit (could that be?). Now for about 4 days, I've gotten no eggs from either Barred, and I'm seeing some feathers in the coop. Nights are getting longer and colder. So....molting? Should I be worried about the Barred Rocks? The poopy butt? Should I clean it up or leave it alone, hoping the molt takes care of business? (She actually put up with me hosing her down, but it didn't get everything) And what are some other causes of loose stool (it isn't bloody and I don't see worms in any of the feces)?
