My RIR Ginger is 2 years 2 months. I can't remember when she last laid a normal egg. Every egg is soft shelled to varying degrees - from a soft collapsed spot to almost shell-less. My hens get mostly layer feed, one small 'meal' a day (cottage cheese, yogurt, tuna, scrambled eggs w shells, oatmeal), occasional greens (never spinach) and free choice oyster shell and grit. Thanks to many of you, I've tried different supplements and feed, from the most expensive organic to ... (with appropriate transitions). Even liquid calcium in the water. Ginger's eggs are SO big that every egg is laid with huge effort - daily. I fear a short life for her, despite her good health. I can only assume this is a genetic issue as my other 14 lay regular eggs. Any thoughts? There are no vets within 100 miles of here who will see a chicken.
