At night our Silkies go into their coop. They've been doing this for a year. We came back at 9 pm after going fishing. I used a zip tie, twice around as always. Cut it this morning and only two hens came out. Found the body of one splash Silkie on the ground less than one foot away. Not a marking could be seen on it and it's body was soft. The black rooster was on the soil and it's body was going through rigor mortis. The black hen was gone. I'm thinking that a red fox, possum or cat could have gotten one, but why would two be left with absolutely no markings on them? We have a four foot chain link fence and there was no sign of digging. Fresh water is put out daily. Looked in the grass for the dead black hen but didn't find her. My daughter was hysterical, she's 5 year old, and kept asking me what would happen if someone came to kill her. Please help!
