You know after a hen has given me 6 or more years of egg laying, they deserve to live out there little remaining time. IMHO.
Yes! I agree one hundred percent, and have 3 or 4 older girls in my flock who haven't laid for some time now. But they let me know when something's wrong - like when a young chick flies out and gets caught up somewhere, and they help the younger pullets figure out what to do. And heck, I know their personalities and enjoy them.
