We just recently got back home from a fishing trip, we'd been gone since 5am. I have my broody Silkies in an open pen with their little cabin. There is no top on the pen. I came back to find one of the females gone, and 2 chicks. I found feathers in a circle nearby (just one feather inside the pen), the corpse was missing the head, and the neck was picked clean. We found the head in all of the feathers. A couple hours later, near dark, I saw a large bird fly away from where the pen had been (we moved it to a more secure area in the chicken coop). My husband thinks it was an owl, I think probably hawk. I couldn't tell what it was...but it was definitely one of the two. It was brown and had a huge wing span. Do an owl and hawk pick the head off and eat the neck and leave everything else intact? Was under the impression that both birds would eat more than just the neck.
