I'm not sure what's going on with her. She was laying fine for a couple of weeks; now she has stopped. She seems to be fine and healthy. There is no sign of inflammation, and she is acting pretty normal. But, she acts like she is laying. She uses the nesting box, scratches around and rearranges the straw, and sings when she is done (or sometimes before). Her bones are still spaced properly for egg laying and she seems to be keeping on a great schedule (she fakes us out about an hour later each day). She also still squats when we reach for her. What could be the problem? All of my other pullets are doing just fine (except for one that never started laying). Any help?
