I would say Mink. I had never lost a bird to a predator before (our dogs keep everything away) this winter. I had picked up 10 show quality silkie hens from a breeder two hours away (the drive was boring and the birds were VERY spendy), and roughly two weeks later I found them all dead in a pile with their heads bit into. I was FURIOUS. So I thought I had patched up any little hole in the barn, but then two weeks later I found my adorable tufted roman goose (she was full grown) dead with a pool of blood around her head. So I removed the patches over the two little holes in the barn (both were gaps under doors), and placed live traps with parts of my goose as bait (that was difficult for me to do). A week later I heard my guineas screaming bloody murder, so I raced to the barn. I found a very ticked off mink in one of my traps. I'm a huge animal lover, but the almost cute animal had to go. I had to kill it, as a didn't want him coming back or else bothering someone elses birds. Long story short, after constant weeks of worry, I can finally sleep again. Lol.
