Encounter with a young crow

[veggiechicken]

This afternoon, an adult crow was squawking on the roof while a young crow was on the ground at the side of the house, behind the side gate. As it couldn't get away amd the dogs were curious. I picked it up and carried it across the road, putting it down on the grass verge alongside some blackberry bushes with plenty of cover.
The two adult birds were flying around and one perched on the telephone line, while the other landed in a tree. Both should have been able to see the chick.
Can anyone explain what happened next?
The chick walked off the grass verge and walked down the road. Whenever a car drove past, it would hop onto the verge, but then walked down or up the road again. It could fly a little but didn't have enough lift to get airborne.
Why didn't it go into the undergrowth instead of walking down the road?
Meanwhile the parent bird was tapping his beak on the telephone line! It then flew into a tree and started to tap, like a woodpecker, on the branch, moving along the branch but, apparently, ignoring the chick.
The other parent bird, seemed more concerned and was flying from tree to tree, crowing to the chick, who didn't seem to be taking any notice.
The chick had white feathers on its wings and tail - sorry,no photos, too busy watching

I don't know why but any attempts I have made to reunite baby birds with their parents have always failed.

They often leave the nest before they can fly and spend a few days on the floor, the parents keep a close eye on them and feed them. You've just got to keep those fingers crossed that a cat doesn't get him Or a kid takes him home! My brother often came home with young birds when we were kids.

"The chick had white feathers on its wings and tail"
I seem to recall that the above is due to lack of Iron or some such nutrient deficiency in the diet.

May of been waiting (impatiently) for a bus and parent was asking bus company where it was, using morse code down the telephone line. (Welsh is not their first language)(left the mobile in the nest)
