Hello i have 13 hens and 1 rooster in a 20 chicken coop. They have 5 nesting boxes, but only use 2. Over the winter they have been breaking their eggs and eating them, even though they had full access to their feed and full access to outside. I thought they would maybe stop while we're heading into spring, but they haven't. I've tried the mustard in the egg and surprisingly they still ate it! The nesting boxes are getting so gross to the point where i'd be cleaning them everyday, when i clean the coop once a week. I have never had this problem before. Any suggestions on how to break this habit, or will I continue having to clean the nesting boxes daily? Ps: the eggs are collected around the time they are done laying.
