Sigh. I'm sorry for that flock.
When we first moved out here, we'd hear coyotes "singing" at night. I haven't heard them in many, many years. Hubby thought he might have seen one on our road two years ago. I'd rather they didn't come back, as we have enough critters that would gladly eat my chickens: raccoons, feral cats, skunks, possums, foxes, stray dogs, hawks, and eagles. Those are the visible threats.
The wild geese and cranes migrating through might bring in the invisible threat of HPAI. Or another disease.
This is why I don't let my flock free range, and have them in a covered run. They are totally dependent upon me for their food, water, shelter, health, and safety. I take that responsibility very seriously.
Mother Nature is an uncaring ..tch. At least the birds didn't go to total waste.
But the larger point remains. In spite of broadly "agrarian" lifestyles, and ample land, in an economically depressed area of the country, my neighbors have almost all chosen to specialize in other endeavors rather than maintain their own flocks for meat/eggs.
We have a couple of people raising cattle, two huge (well, looks huge to me) grape orchards, lots of people commuting into town for other work, I believe someone else nearby raises goats, another specializes in hunting dogs, and a lot of land used for either timber or personal retreats.
