A few days ago I went out to my barn where the winter coop is and found my littlest silkie dead in the little house. She was kind of stretched out, she wasn t eaten and there was some blood and missing feathers on the back of her neck. The other 3 girls were fine. We thought she had just died, and maybe the other hen pecked her to move her out of the next box. The next day, another healthy (seeming) hen, this time a salmon faverolle, was dead, same exact appearance. So I brought the remaining silkie and faverolle into the mudroom and put them in a big rabbit cage until we could figure out what was killing them. So this morning I went out and my last faverolle was dead, right in my mudroom in a closed cage! What is going on?!? Is my one silkie a maniac? She is the last hen standing! Could it be that they are dying and the silkie is moving them by their necks and that is why they look plucked? Is there a bizarre disease that could cause this? I am up in the dead of winter where there are not snakes or anything, and any predator would have had to squeeze through 1 inch bars right in my house. Please help. I don t want to keep an serial killer bird, but I don t want to give away one that has a communicable disease. The birds seem completely healthy and happy when I put them to late at night and they are dead by first thing in the morning. I am heartbroken and nonplussed.
