Can't be a hawk cause it was dark.. The thing is he has no cuts or blood that I saw and was able to run/fully alert when I tried to catch him. It's almost like something walked into the coop and just ripped some feathers off without hurting him, maybe with my quick reactions running outside I saved him before he would of died but there was nothing in sight. I thought maybe it was a human but the run door was closed not open.
Edit: Made me freak out alittle cause it was so weird and unorthodox. Had to have a couple of beers after that...
It is possible that it was an owl. Even at dusk, we have plenty of them here!
