Years ago we lost a huge, thickly-branched limb out of one of our large trees. Getting it cleaned up got pushed further and further down our "to do" list, to the point that the downed limb became a permanent fixture, as it wasn't in the way. One February morning my favorite pet chicken was foraging near that tree when a young eagle attacked. There were two fistfuls of feathers about 5 feet away from the limb, and two fistfuls down inside the tangle of branches where the eagle had reached down inside as she was running. But she made it to an area where the eagle couldn't reach in, and if flew away as we came running outside. That downed tree limb saved her life! Free range chickens need places they can find cover if you live where raptors fly.
Hurray! That's exactly what I'm hoping for. Your hen had quick reflexes and good luck on her side as well. My branch bunkers look not too bad. Husband likes an open field aesthetic, so he might complain. And a bonus for the sheep, who spent the day browsing on the twig ends.
