Hi! I have 5 laying hens and have one girl that started laying no shell eggs a few months ago. We have tried oyster shell, ground egg shells, upping protein and vitamins in their water. So far nothing is working. She is the only one we are having trouble with and this has been ongoing for months. They seem to be eating the broken egg too, which I heard is a bad thing? To go back a bit, she was laying eggs that were so large they were getting repaired half way through. Now every egg she lays is shattered once it hits the shavings. Is there anything else we could be doing for her? We got her already laying and I have no idea what her age is, nor do I know how long she has been laying.
