We recently, about a month ago, adopted 2 (seemingly healthy) Rhodies we named Laverne and Shirley. They are both very sweet, Shirley is quite chatty and they have both been good layers that integrated well into the flock. While Laverne and the rest of our free ranging flock seem to be happy and healthy, Shirley has over the last 1-2 weeks developed a very dirty vent, dark loose (and stinky!) stool, and over the last couple of days I'm finding soft shell pieces and egg contents in her feces. She otherwise seems fine and I'm not sure what to do for her as the vet is not an option right now. Any suggestions?
