I've been battling that with one of mine. The rest are great and go to the free choice oyster shell, but her, not so much. I feed game bird crumbles without calcium. So I mixed in regular layer crumbles with the game bird crumbles, seems to be doing the trick. 3 eggs from her this week, all since I added the layer crumbles, all with harder shells. Are they new layers? last summer I also had a different new layer that layed soft shelled eggs for a couple of weeks until her piping got in order.Got 2x soft shelled egg this morning![]()
