Hi I have found this yolk colored poop in the run over the last week. Its under the roost and in the run. I have one hen Robin, mature enough to lay. She has not laid since our other hen and chicks were separated into the "chick house". I anticipated she would start laying again but nothing as of yet. Our flock in this run consists of one Tom, Robin, one teenage Jake and teenage hen, and four 9 week old Jakes.
