4 week old walking on hocks

good, chicks can't have adult food. you are going to have to watch out for blisters on his legs from walking on them. and like coach723 said,

Hock sitting can be a riboflavin (B2) deficiency. I would get a human vitamin B complex supplement and grind that up and give to that chick. You can mix it with a bit of feed softened with water, or a bit of cooked egg to get it to eat it. B's are water soluble, so little risk of overdose.

it might be due to not enough vitamins

Twice a day I alternated between goat b complex and poly vi sol without iron. the little guy was better in about a week.
