Is this normal? Please help

I recently noticed that one of my Barred rock chicks chirp drastically changed. She’s eating, drinking etc a few occasional sneezes. No nasal drainage. And no smell from beak. I’m hoping this is all normal but could it be more?!

I didn't hear nothing wrong. Looks like it's ready for some more room or exercise. If it's warm out taking them out for short trips is a good idea at that age.
