I spotted on the grass verge right by the road a small chick, which kept trying to run into the grass but couldn't seem to get through. We watched a while and it didn't seem to be making any progress, the adult was still in the field just over the hedge. I was in two minds what to do, the chick was so close to the road, if it ran the wrong way... I know it's best not to interfere. In the end though I couldn't just drive off.
It crouched in the hiding position as I got close but I scooped it up quickly and let it run off my hand into the open entrance to the field where the adult was. It immediately got close as I left them to it. I felt much happier having done this and think it really would have struggled to get around that hedge.
