My flock of nine chickens and two guineas have been free ranging for about three months (they're 6-7 months old). We have a fully fenced (chain link) acre property and live in rural East County of San Diego. I came home yesterday to find one of my barred rock hens lying dead in the yard. I am just devastated. She was a beautiful hen and a daily layer of large brown eggs. She also was one of my friendliest girls and would hop onto the arm rest of my chair when I sat in the chicken yard. So sad and such a waste - she was raised by hand from a day old chick When I checked on the others, initially two chickens and a guinea were missing. I shooed them all back into the coop and tried to find the others. One was in a nest box, and we found the other of my barred rock hens crouched under a bush in the lower yard (after about three hours searching) injured, but still alive. We found the guinea hours later across a busy street in a neighbor's yard, completely unharmed. Thank goodness guineas honk so loud - she was easy to locate. This happened between 0745 am and 1100 am. Our neighbors said they have seen coyotes in the area as late as 8 or 9 in the morning. The girls are all locked up at dusk and were being let out after sunrise, but I guess they'll have to learn to live cooped up unless we're home and in the yard. I just can't take losing any more of them. I am wondering what predator might have done this? We're thinking coyote, but it's strange the dead chicken wasn't eaten. She was completely intact, feathers and all, except a hole in her center lower back about an inch around. The injured chicken has most of her tail feathers pulled out, wounds on her back, just above her tail, and a large, but not deep gash under her wing. There were tons of feathers scattered in one area of the yard. It appears that she was grabbed and shook, and then escaped. Any ideas on what might have gotten her?
