DH killed the one that was barely alive and it made a noise that was very similar to what I thought was the fisher cat. It was a necessary act. She was pretty messed up. So, it may not be a fisher cat but whatever it was can move - and fast. I was out there in a shot since I've been sitting near the window listening with the fans off.
We baited the two traps with the dead hens and caught three of the remaining black sex links. I'll tell you what though. My RIRs were hiding out in their coop, quiet as mice. I swear they were playing dead. Same for the guinea hen and her Aracauna companion and the turkeys.
I am very deeply unhappy right now. They were pretty birds, sweet and smart and in less than two days, I may only have three of them left.
