I've been seeing a lot about hawks lately on the boards, and unfortunately, we lost a hen last week to a redtail. "Buffy", our bigest, laying hen was killed right outside our living room window by a massive hawk. He flew off without even eating anything. Just snapped her neck and flapped away. My kids were devastated. Inevitable as chicken loss is, this is actually our first pet loss as a family, so emotions were a little raw. Anyway, I have been reading up a lot on hawk deterrents, and had an idea. While we do have a good, sturdy coop, and a covered run, we had been letting them free range the yard every day. I keep seeing references to fishing line being a good stop-gap measure, and I kind of ran with it... We have 2 outbuildings in the yard, and a 6ft stockade fence around the whole thing. All in all, we're talking maybe 1/4 acre. Great yard, but nothing huge. My husband and I have been out there "spiderwebbing" a crisscross of fishing line ALL OVER the yard, effectively covering the whole thing. Now, this is not a perfect grid or anything - there are some larger gaps measuring several feel across which need to be addressed somehow. My question is: will this even work? Or will a hungry hawk slice right through our ad-hoc deference system? Have any of you had success keeping hawks off your chickens by covering large areas with fishing line? Remember, they are protected on all sides by a solid wood fence - it's mainly the air attacks we're worried about. Short of putting a lid on the whole yard, this is the best we could come up with to let them roam a little. Are we wasting our time?
