I am now down to just one RIR hen. It all started about a month ago...I bought two younger RIR hens and one Golden Silkie A week ago, I found what was left of my silkie. At that point I cut back the elm tree that was touching the top of the coop. I added flashing around all the trees last year to keep coons and possums from climbing the trees. Last Tuesday, I found one RIR to me missing, and the other to have its head and neck missing. I found her just out side of the coop entrance. Today, I find the rooster missing without a trace, and one of the older RIR with her head and neck missing, body slpayed open and a wing torn off. I found the silkie like this as well, but her wings were intact. I did take a pic of the carnage. Nothing was caught in the trap. I do know that coyotes and bobcats are in the area. I have trapped and killed plenty of coons, possums and the occasional skunk. Thanks!
