Hi, We are new to backyard hens, and we have a protected coop that our 4 hens stay in each evening. They free roam the backyard and we haven't seen any predators other than a single hawk months ago (1x only) that the girls ran off. Early morning, yesterday one of our hens was killed and it happened to be the 'lead' hen (mother hen? matriarch?- not sure of term). There were feathers in 3 different areas of the yard and she was far away from the initial area of feathers. I'm wondering if it was a hawk, wouldn't we see the hawk again today or back again yesterday afternoon? Is there a way to determine 'what' killed our hen? Also, I"m worried about the other three hens. (they are now up in their coop and not running free) They are going back to the site where she was killed, and clucking non stop and seem more frantic. I'm not sure how to help them and thought I'd ask here.
