I'm sooooo sorry !!! It's terribly creepy to think some freak job has been walking around your place and helping himself.
It's just sick !!
Good luck on finding your roo. I know you don't have pictures but maybe you could put a description of the bird and the man who stole him. Describe his vehicle etc... somebody might call you. Plaster those STOLEN notices everywhere. Feed store, grocery store, gas station.....
