Last night when we got home from church, we heard an owl hooting in the neighbors yard. We let our chickens free range in the day, but keep an eye on the sky for hawks circling. The crows help in warning the chickens. I've never had to deal with an owl. Never heard any before. Do they hunt in the daytime or just at night? Will the crows help deter them as they do the hawks? As they say..." know thy enemy" I need to know what to expect from owls so I can protect my hens.
