I think my week old cornish x chick has spraddle leg what do I do?

[flstout]

My chick can't stand on its own it just keeps laying down with its head on the floor of the brooder!
I just tried using a band-aid to help hold its legs in place and now it just keeps falling over on its side.
I don't know what else to do, does anyone have any ideas?

When I taped his legs and put him back in the brooder he just rolled over on his side. He doesn't seem to be able to sit up at all on his own or stand for that matter.
