There is no reason for that not to happen. There are plenty of ovum left in her. I wonder what sparked up her hormones?Any one ever have a 7+ year old hen who has been laying a few eggs a year for a couple of years start laying 2 or 3 eggs a week for 4 months? My old Lady EE started laying blue eggs again on Christmas Day and has continued to lay 2 or 3 a week since with no signs of stopping. Little pea comb remains bright red.
