So I got some decoy birds at TSC for $10 each; they were 50% off from two weeks ago, which was awesome. I got them in the hopes that they'll keep the possums and the hawks away this year. I plan on putting the hawk up during the day, and switching them out at night,so the owl and her lovely eyes will keep the possums from skulking nearby. Everyone, meet Archer (the hawk) and Hildegarde (the owl), and they are my turncoat flock guardians. (Archer and Hildegarde chilling in the living room) But my question is, will they do a good job? I've read various places that decoy birds are a valuable tool in protecting a flock, but I'd like to hear it from you guys. Has anyone else done this, and does it work effectively?
