My five year old Buff Orphington lays three eggs a week and my five year old Barred Rock lays about two a week. My four year old Silver laced Wyandotte lays about two a week. My three year old girls lay 4-5 eggs a week. As you can see, it varies. My 'senior' Buff Orphington is also the Alpha chicken, as well as one of the best egg layers. You're as young as you feel!
