We came home the other day and found our black silkie dead in the yard. Feathers were everywhere, including some RIR feathers. She looked like she had been partly plucked, her stomach was opened and mostly eaten. Our other chickens and ducks were hiding under our deck unharmed. DH thinks it was a hawk because he sees them flying around our house. I think it could have been a dog because our neighbors can't keep their's in the fence? Any ideas? We live in rural New Hampshire. We want to get rid of whatever it was, but not just killing everything.
