I had a red star that lived to almost 9 before she went down hill quite fast. I don't know if the last 2 years she was laying anything though since we had other birds laying the same color eggs.
I also have a calico princess who is almost 2 and still laying like a pullet. Even now in the middle of winter, she lays every 2-3 days. *Going to add that she lays eggs with meat spots regularly. Unsure ifnthis will ever affect her noticeably as they're quite small, but it's at least half the eggs she lays that have them, prpvalt more like 2/3
And yes, sexlink is not guaranteed tobmean high production. I can make pure sexlinked Cochins or sexlinked silkie crosses that are unlikely to lay anywhere near a red or black star sexlink, but all 4 of those can be sexed at a day old
