My poor little silkie hen , Raven, was dragged out of her coop by a large hawk while she was sitting on eggs. My Roos all ran and hid under my car while the poor defenseless hen had her head torn off. I had gone across the street for only a few minutes and had no idea what was going on.......I have, or so I thought, hawk proofed my coop but some how he not only managed to fly through the small opening but also get into the coop it self! Why go through all the trouble for one weak hen??? I am so frustrated with this. I can't seem to keep them away........ I have decoys, reflective owls, wind chimes, Even loud barking dogs! I don't understand why they keep bothering us. My neighbor that's only three houses down has chickens, even silkies, and they have no problems. Can anyone give me any advice to prevent this from happening?!?!
