I was riding my bike in an industrial area on the outskirts of Boise when a family of Killdeer, including a few chicks ran out in the road. There was grass nearby and I tried to herd them that towards it to prevent the chicks from getting run over by trucks and cars passing by. I had my HDV camcorder available so I captured a little hand held footage of one of the adults displaying the "broken-wing" behavior and a chick running on the road. The chicks were eventually led to the grass where they were quite well hidden and safer unless they run out into the road again.
Birdwatching.com has a good description of Killdeer behavior and the ability of the chicks to start running as soon as their feathers dry after hatching.
