I have read all about egg deformities and constantly refer back to the article and pictures in the gallery. Well enough, so my hen has been giving me eggs regularly and all have just a little deposit at the apex side. She had been on layer feed her whole life before I bought her three weeks ago. She is about a 18months old. So, since coming here, she has been getting some other food, not just 'treats'. Lettuce, spinach, some crickets, corn (can and scratch), black sunflower seeds, cucumber middles, squash, and dried oatmeal. ALL in severe low quantities and after I feed them first thing in the am with their layer pellets. Where am I going wrong or how can I reduce her calcium if I have to? I guess the deposits on the eggs are not life threatening.....
