They've been really bold this year, likely as a result of loss of habitat due to development. Aptly, the latest 5 acre subdivision at the end of our road is named Coyote Run... We have a pretty active den down the hill and across the creek, so it was not a surprise to lose a couple hens with the dog gone for so long. She's pretty good at sounding the alarm and likewise smart enough not to venture into the woods on her own.
