My barred rock (hatched at the end of March) has been laying for a little over 2 weeks now. But every egg she's laid so far has been shell-less. She free ranges for about 6hrs out of the day, has free access to oyster shell, and is on Southern States layer pellets. I also feed my flock fruit/veggie scraps. Her flock mates that hatched around the same time, who have also just started laying all have "normal" eggs. Should I be concerned? (I am, lol) I know that shell-less eggs are common in New layers, but she's laid approx. 10 eggs now, all without shells. Is this normal?? Is there something else I can give her to help her?
