My little girls are all grown up now and are laying! The eggs are small still, but quite edible and quite tasty. However, Im not sure who is doing it, but one of the girls lays an eggs with a slight whitishness to it. All my girls are brown egg layers. This whitish color rubs off with water. What does it mean? I recently went from one brand of layer feed to a 16% layer crumble. I like my results. the eggs are firmer and the girls seem to have more energy. Im also feeding them a Purina scratch with barley, oats, corn and I cant remember the last ingredient. Over all though the girls look healthy. Im just curious why one is laying white on the brown shell. it makes the egg look almost pink. Is it too much calcium?
