I have a 1.5 year old who lays a light greenish to blue egg. Her shells are always thin despite giving eggs shells back, oyster shell, extra calcium tablets with magnesium. The works. We’ve tried it all. We get 2-3 eggs per week with consistent thin shells and the color of her egg is much lighter than it used to be. Wee thought maybe egg drop syndrome since her whites are quite runny as well and her egg count had diminished. We feed Kalmbach henhouse reserve. Well, we found this in an egg the other day… what could it be?
