I am SO sorry. I know just how you feel, I lost 18 (all my hens) a little over a week ago. We were not fortunate enough to find out what it was, which has been very hard for me. At least you know what happened. I'm SO glad one of your girls got away. My roo survived, but they'll break your heart trying to find the others. I recommend you find a buddy for her as soon as possible. My dear friend gave me two of her girls and Big Daddy is much happier now and it helped me to see chickens poopin' and peckin' on the property again. It's heavy duty lockdown at night around here but at least I don't have to worry.
Regarding shooting the predator....endangered or not, if it's killing your livestock you can kill it. Our local Fish & Game told me that it was up to me but it was legal since I was not in town limits (for shooting a firearm) and it ate my livestock. A good example of this was the incident in Montana where ranchers killed several endangered wolves that killed their livestock.
I'm just so sorry.....
