So about 3 weeks ago. I picked up a RIR Hen from a friend. The last 2 days all she has done is sit like a flat pancake on the ground and now refuses to come out of the roost. When I go near her to check for eggs. She wiggles, but stay there. There is no eggs underneath her atm. In the pecking order, she is the last. So is she broody or Sick. Suggestions please.
