I have an Isa Brown hen, Layla, who has stopped laying. She is only 3 years old. She hasn't layed since her best friend got killed by a predator (layla was not injured) when she was 1 year old. Before that she layed everyday perfectly. After her friend was killed she was our only hen for a while. We thought she was lonely so we got some more and still nothing. Could the emotional trama of seeing her BFF get eaten stop her from laying forever? Or do some chickens only lay for a few months? Has anyone had anything like this?
