Chicken Standoffish and Slow

[chicksofclaridon]

I have a 10 month old Silver Laced Wyandotte. When I went to let the girls out of the run (6 in total) they all got excited and ran out the door like a kindergartner at recess, except for Gypsy the Wyandotte. She was fine when I let them out around 11:30, but this evening she is walking a little rigid, she is puffed up with her head pulled in, she walks slowly and off on her own away from the flock. She will take a few steps, then slowly lay down, like she is sitting on an egg. She will just sit the for ages, then eventually get up, take a few steps and do it again. She laid an egg yesterday. I checked to see if she is egg bound (to the best of my ability) and it doesn't appear she is. She will drink and peck occasionally at the grass, I haven't noticed her eat but this has only been the last 30 minutes or so that I've noticed this behavior. Attaching some pictures. This is totally out of the norm for her. Any thoughts? Anything I can do? All other chickens seem to be fine.

Last picture is her in the corner all by herself

Wonder if she's considering going broody?
Is she eating/drinking/pooping ok?
Have you checked/feel her crop? It should be empty in the morning, full in the evenings. Squishy? Solid? Play dough?

She is drinking a good amount and she’s eating but only off the ground for some reason (at least this evening I haven’t seen her eat from the feeder). Crop was full but I didn’t feel it, she seemed stressed as it was so I didn’t want to make it worse (she doesn’t particularly enjoy being touched). Broody could be a possibility— I have a camera in their coop and I looked this morning and noticed she was in the nesting box while all the rest were roosting/asleep. That’s the first time I noticed this behavior, although their was no egg. This evening she hopped up on the perch with the other girls as usual, so she isn’t hiding out or sleeping in the nesting box.
