I've heard that stringing fishing line across where you keep your chickens can deter hawks. Something about the hawks not being able to see the fishing lines but it freaks them out when they hit them. Anyone heard of this? My chickens are kept in a very large fenced in area where netting across the top is infeasible (approximately 1/4 of an acre). I've never had a hawk kill any of my chickens but I know someone a few hours away that recently had a full grown RIR killed by a red tailed hawk. We have a lot of red tailed hawks in my area and I've even seen them watch my chickens but never attack. Red tailed hawks are protected so I can't just shoot them unless I actually see them go after my chickens which would be a little late in my opinion. I'd rather practice prevention then have to burry any of my feathery pets. Anyone have experience with using fishing line as a deterrent?
