Since she had an empty crop ea rlier roday, I would think there is no crop problem. It may well be a pecking order problem, but chickens with reproductive problems may not eat enough. Symptoms vary with each hen with internal laying or egg yolk peritonitis, and may include loss of appetite, sleepiness, waddling, upright posture or preferring to sit or lie down, separating oneself, and usually not laying normal eggs. It is good that she is accepting food. I have multiple water and feed stations inside and outside my coop and run during daylight hours to let the meek ones get a chance.
