Sick chicken please help

I agree with the other poster.. this doesn't fit binding.. but maybe sour or blocked crop.. what are droppings looking like? Please do a crop check. Share her age, standard feed routine including treats and supplements, any recent changes or additions?

How does her vent look.. is it pulsing, swollen, red, bare or anything like that? When was her last egg? Where in the world are you located approximately? Add your general location to your profile if able as it can help folks make their bast suggestions possible at a glance. How many flock members? Ever treat or check for internal/external parasites before?

She definitely has something "off", you're correct about that. Hopefully we can identify it and help y'all out a bit!

her vent is light pink, though pulsing a bit. we did not feel an egg inside. her last egg was yesterday. We are in the boston suburbs, and it is cold here. we have 5 flock members including Katinka, and we have not checked for parasites before. I wonder if it has something to do with the cold.

I would re-check her crop first thing in the morning to make sure it emptied.
Get some photos of her poop.

Does she lay fairly consistently? I would feel below the vent between her legs for bloat/fluid.
The limping, I would wonder if she's having some reproductive issues.
A healthy bird should handle cold well if they have shelter. You don't mention any other birds having difficulty. I would keep her relatively warm. Work on getting fluids into her. I understand we feel a need to see them eat something, but hydration is important. Once she's drinking, then offer a little wet feed.

We kept her inside for a week, gave her lots of electrolytes. She started getting better, so we moved her to the garage to 'test the waters' and give her more space. She made a full recovery, is back with her friends now, and is working on laying an egg! Thank you guys!!
