I don’t usually splint a sprain. A warm and quiet hospital box, a lot of rest, with easy access to food and water is what works best for my chickens. I hope you can determine for sure whether it’s a break or sprain. Is the leg dangling at all? Is it functional? Is he placing any pressure on it (trying to stand and walk on it)? Please continue to update us with how he’s doing. Very lucky little chick to have you.Thanks for the additional information. We're still keeping him (or her) warm & giving him a lot of attention. He's eating and doesn't seem too distressed. We're hoping for a sprain, not a break b/c I'm assuming that we wouldn't need to splint/set bones with a sprain. Or am I wrong about that?
