Whole flock shut off

[Sandersfunnyfarm]

I got a buddy who has a flock of 16 leghorns, it's been 7 days since any layed an egg. It was steady 16 eggs a day and one morning there was nothing. They don't seem sick. They have food. No predators have been around. Has anyone had this happen. They are less than 1 year old.

Do they free range?
