Is she a Delaware? Our poor hens. The industry that has made them egg machines has wreaked havoc on their reproductive system and their livers. When a hen comes to an age to lay, their liver structure changes appreciably. If you combine this with the fact that the industry took a layer from laying only 10-15 eggs per YEAR (naturally) to 200-300 per year, heat stress, and diets high in energy (sugar); this makes a hen predisposed to Liver Hemorrhagic Disease (LHD). Also, white egg layers are twice as predisposed to LHD. You can add milk thistle and flax seed to their diet to lower the risks.
