Thank you for chiming in! I want to help but only have little eggbound experience that was remedied by applying olive oil and adjusting my hens' diet afterward. No personal experience with this type of chicken, though I do know how fast they grow.You said she has a big hard lump in her abdomen? Is this still there? Did you insert a finger into the vent to feel for an egg?
Does she have any other symptoms? If it were me, I would immediately bring her inside to a warp place. Will she drink fluids? Does she have any other symptoms rather than the walking? What do the bottoms of her feet look like?
What do you feed her, how much and how often?
I hope we can help you figure out whats going on.

Hens go broody when you don’t want them to… and won’t go broody when you do.
May I add that putting an egg bound hen in a steamy room after popping calcium (calcium pills or a Tums) into her beak immediately is a better remedy than soaking. Hens who are struggling have trouble glancing their body temperature, so soaking can cause hypothermia, I learned this the hard way.
I followed a thread were a member helped her hen pass an egg by placing her in a steamy room, the egg passed very quickly along with the extra calcium. Just a note I thought I'd add.
