Injured leg 1 week old chick

[Saraschickens]

I had people over yesterday, and there were kids. I went against my best judgment and let them hold the chicks for a couple short 5 minutes bursts throughout the night (without me). I had watch a few times and corrected anything I saw. My kids are very experienced with chicks and good at speaking up for the chicks.
I honestly knew better, and a hate these kind of learning experiences. But this morning, sure enough, one was limping. I couldn't see anything swollen, but it wouldn't stand on one leg. So I gave it a split (straight legged), and put it in a sock sling in an upside-down cottage cheese container. We've been giving it food and water. It has a little wall around it so the other chicks can't jump on it. I have the thermometer next to it and it's at 94°, the chick is 1 week old.
What should I do?
How long should I have a split on it?
Do I split only the leg that's bad, because with only one leg splinted it can't walk at all, as opposed to before it was 1 legging it around?
I've not had good luck with leg injuries and having the bird live.
Thank you to anyone with advice.

Could it be less of an injury? Like a sprain?
I'm giving it Save-a-Chick in the water as well.

If it were a sprain and not a break, how long would it take to heal?
And how soon would I know the difference if it were a break or a sprain?

So just an update, I wrapped it's leg with vet wrap to keep it straight. I unwrapped it daily to check on it and re wrapped it. She was limping and didn't want to walk on it at all. It happened on the night of Monday, I found it Tuesday morning, and wrapped it. I unwrapped and re wrapped Wednesday and again Thursday, and when I went to do it on Friday, her limp had improved so much that I decided to leave it unwrapped. She got around ok, and was hard to find her each time. I could tell who it was once I'd find her but each time she was faster and harder to find. She stood a little odd, and liked to stretch her legs and wings on each side. But within a couple days she was all healed! I don't even know who it was now! So, a happy success story!
