I'm sorry. I thought I had a mink problem. I had something killing my birds, lost 15 in 1 evening between 4-6pm in the fall. Bodies everywhere with broken necks, but a couple were headless. It was horrible. Then it started picking off 2-3 every few days a few months later. I would find the body because it couldn't get the birds through the fence. My dog and I stalked it, and I saw it a couple of times, but it was so darn fast that my eyes couldn't focus on it. It was smaller than a chihuahua, so the only thing I could think of was a weasel. Then I was informed by a wildlife biologist that we don't have weasels here.
It turns out it was a mother bobcat teaching her young to hunt. I can tell you a baby bobcat can kill and carry a chicken (rooster) 5-10 times their size. Bobcats will not stop once they find food. I ended up losing 23 birds total.
Awwww, they are adorable!
