Not super urgent, but one of my hens seems off

I noticed a few minutes ago that my EE hen is acting a bit odd. She turns four in two months. She is moving almost in slow motion and not showing much interest in foraging or scratching even though I just let them out of the run. She perked up when I gave them some mealworms, but soon reverted back to what she's doing now. I thought a minute ago that her clucks almost sounded gurgly, but I just picked her up and she sounded normal. My other two are acting normal, I did see one of them sneeze once yesterday but other than that they're all good. I don't know if she's eating or drinking, I just came outside. She hasn't laid in months, she's generally not the best layer. She's never gone broody. As I write this, she just laid down - not dramatically, just settled down like she's sitting on an egg.
This is my fault, I have two chicks inside and like an idiot forgot to wash my hands in between handling them once yesterday. I've seen the chicks sneeze a bit but they're very lively and are otherwise doing just fine.

Update: Gave her some egg yolks which she ate and after a bit she drank. I waited out there for 40 more minutes to see her poop lol, so here's that picture:

Pretty runny, but some poop is just like that to my understanding...? I then picked her up and put her on a roost in the run to see what she would do, and she hopped over to the other one that's the same height, paced around a bit, but hasn't jumped down, which is a bit strange for her. She seems to be getting sleepy now, I'm going to get her down from the perch so she doesn't get stuck or injure herself.
