We had our first predator loss yesterday. We found lots of feathers and only a tiny piece of bone less than an inch long, but no sign of any flesh, other bones, head, etc. We think hawk because of telltale whitewash streaks nearby and the fact that a red-tailed hawk who sails around regularly was sitting on the fencepost near the chickens later that day. Do hawks consume the entire chicken? It's also possible that it was interrupted by our dogs and flew away with the remains. The chick was a 6-week-old meat bird that weighed around 4 pounds.
