Will my chicken lay eggs?

Hey, I bough 5 lovely chickens in the begging June, they was about one month old at the time. after having them for one month three foxes got in the coop and took all of them except from one.

After a few weeks i bought new chickens for company for the survival, she don't really like all of them but anyhow. What I am afraid is that my chicken got so scared that she's not able to lay eggs anymore, is that possible or just a myth?

Best Regards, Erik!
