I just saw one swoop low through the yard, the girls will stay locked up for awhile today.
You could always lobby them to put in a wind farm next to you. There used to be eagles here in the winter but not since the (expletive deleted) wind farm was put in. I still have an occasional hawk come through and even an annual visit from an Osprey. The only poultry that I have lost to birds of prey are to Great Horned Owls and only during the night. They often roost in my trees during the daytime but have not bothered the poultry during the day.
I thought I lost one of my bearded silkies to a hawk the other day when I couldn't find her for a day. Turns out that she managed to get into the turkey pen and got stuck under their coop. My silkie cockerel "told" me where she was. Good thing or I'd have never found her.
Coco watched the drama and kept eating grass, apparently not at all concerned about the presence of a one pound rabbit. Big Bird gave that rabbit the stink-eye until I put her in for the night and put on a great, flapping, squawking drama every time it got too close. I think it hung around for the entertainment value. Birds - they never fail to surprise you with something new
