I had a buff orpington that never layed at all. I figured last year she would die, as she acted like she was egg bound, but then she rebounded and lived another year, never laying an egg that I know of. Her comb was always dry & light pink. Last Friday I noticed here comb was suddenly almost all red, by Saturday she was standing around & by Saturday night she was gone. The other BO layed until February, almost an egg a day, but they were always thin shelled & rough. More protein or more calcium nothing worked. She is still running around and the other week I had a yolk laying in the nest box that I think was from her. Her comb is always red, but I never see any eggs. Don't know if she will fade away too. Never had this problem in 16 years.
