I have two almost year old girls. They eat well, enjoy life, are free range during the day and have ano outdoor run after dark with an indoor coop. They eat bugs, chicken feed and grit, plus and kitchen left over a week have. They are comfortable following us around in the yard and let us carry them. They are especially friendly with my toddler and he usually has the food. But... they have never laid an egg. Ever. Their nests boxes are empty and untouched. What am I doing wrong?
