Hello,
This can be normal for some chicks. I would strongly suggest, however, that you make sure it has access to water. Without water during those first few hours can cause more problems. If he/she isn't drinking on their own I would suggest you force water it. This will help keep it's body hydrated throughout the first milestones of development outside of the egg.
P.S. Watch the chick closely as you don't want the other picking the one which isn't walking yet. Chicks will oftentimes do this as a process of natural selection. Just keep an eye on it and if he/she needs to be isolated I would then do that.
