I currently have about 150 hens in pasture with 5 hoop houses that move daily. I know it is illegal to shoot any bird of prey. And in the last 10 days I have lost 15 hens do to three hawks. I know for sure there are at least 3 as I seen them sitting on top of the hoop houses one day. What can be done to scare them away? I basically have the hoop houses and 4 rolls of poultry netting to keep the birds in and predators out. And the aerial predators are doing huge damage. I won't have any birds left by the end of the season at this rate. Ideas Please!!!!!
