I raise pigeons and have had them come back bloody from what I would assume to be an attack or shot at. Had hawks chase them back to their loft, have not had one in the loft yet and hope I never.
It's amazing how much pigeons can go through and still return. Do you race by any chance up there?
I've had one in the loft, and one in my garage where I was breeding some pigeons. I wasn't real thrilled with that.
