Had one girl lay 5 eggs 2 weeks ago. Waiting for her to clutch again any time now. My big old girl who used to lay 2 clutches of 7-9 eggs a year has not done any laying in the last 2 yrs. This will be her third. She is healthy eating acting otherwise normal. Have not seen any mating activity with any at all since early spring. Not sure if its age or what. actually thought they continue reproducing their entire life. Any thoughts?
