At night during much of year we sleep with windows open in part for energy conservation. This enables me to hear what is going on out in yard. I here chicks on porch, all roosters crow, wildlife (red foxes, coyotes, great horned and barred owls, occassional coon squabble, white-tail deer snorting, etc.), and chickens cackling / squalling in response to predator. I frequently bolt out of bed and house with flashlight to see what is causing ruckus. I can and do chase oppossums and coons through pasture wearing nothing but shorts. Coons not as fast as ticked off human, opposssums should not even bother to run. What has bothered me is that I can occasionally hear neighbors' chickens being taken by predators. From inside house I usually can not determine whose so I get my light and run out to porch. Neighbors seem to sleep thru or are otherwise unaware of what is going on. Calling at 2 AM is not popular in these parts and intervening might get me shot. Hearing neighbors loss in process is almost as distressing as loosing my own. Neighbors do seem to enjoy more conditioned air and sleep more soundly. They also loose more birds, alot more than I would tolerate.
