We've got 3 groups of chickens - one 16 weeks, one 5 weeks, and one 10 days old. One of my older pullets laid her first egg today, and we're obviously excited. But... they've had a little bit of the starter feed medicated for coccidiosis. When we were cleaning the cage for the 5wk babies (which is inside the big coop) their feed got dumped on the floor of the hen house, and the older pullets ate it. Does this make the egg unsafe to eat?
