I have a chicken coop/run for my younger pullets and cockerels. We got some of them the 3rd week of February at the earliest and some during the month of March. It is now May 25th. Today we found a decent sized brown speckled egg in the run. It is the same size our 5 month old Maran lays and similar in color. What other breeds can lay earlier. We have a mix of different breeds inside the coop/run.
