We've gotten 3 eggs in the last 24 hours from our 17 yr olds. They are small and distinct different shades of brown...2 dark and 1 light. Will the eggs get bigger? Can we eat these first ones? Will the same chickens (2 barred rocks and 2 red sex links) lay the same color? This is exciting. My wife loves to hear the squawk....she runs out to see if she can see who laid it.
