I have a hen that has been having loose poop but this morning when I went into the hen house it was all over the roost and the floor she also has it all over her feathers in the back I have removed her from the flock and I will be cleaning her up . What should I be feeding her and should I keep her seperated from the rest until this clears up?? This was a serious amount of diarrhea she doesn't act sick and is laying but I haven't been eating her eggs, not sure what is wrong.
