Funny, I had a chick hatch yesterday that did the same thing. It was trying to scoot around on it's butt for a few hours...sticking it's legs out in front. I went ahead and put "spraddle leg hobbles" on it even though I didn't think that was the problem. Within a couple of hours it was up...
Highly unlikely at this early age. Some chicks take awhile to get their bearings. Are his legs ok? Not spraddled?
Typically with wry neck, they tuck their head forward into their chest and if anything, roll forward. I would just give him more time.
