The reason I thought of Sumatra chickens is because they are supposedly one of the closest domesticated breeds to the wild red jungle fowl. This makes me wonder if they have the instinct to fly to an improved position or at least cover enough ground in one hop to evade some predators. A wolf, not a chance, but something with a more limited range of attack possibly. It seems like my leghorns don’t evade by more than fifty feet. Most of that is running or near the ground. Even a beagle could catch one easily I think. But if they lifted off and went thirty feet up into the nearest tree, most predators, not all, would weigh the ease of capture vs moving on to more convenient prey. A canid wouldn’t wouldn’t be the least deterred.
