I think it is about to start. Previous years varied greatly in terms of what occurred. https://www.backyardchickens.com/threads/great-horned-owl-fun-in-2016.1090039/#post-16735188 This year I have many fewer chickens and seriously upgraded confinement plus some game cams to see what will be going down. Cotton-tailed Rabbit abundance higher than I have ever seen. Rabbits forage in plan sight of Great-horned owls all night long in locations I can monitor. Before all is said I think this will get interesting.
