pullet resting/walking on hocks only

[Jenfire11]

good afternoon all, i have a 3 month old gold wyandotte that suddenly became "lame" yesterday. she is not laying yet. she will not stand on her own but will put her feet down if i hold her body up. she had no problem keeping her feet down while i was soaking them in an epsom salt bath. i did clean her feet and don't see anything that looks like bumblefoot. she is moving around using her hocks and they actually look bruised (is that possible?) i read a bunch of threads here but i'm not sure any of them apply directly to my situation. for now i have this pullet isolated in a dog crate with food and water. the water has rooster booster b12 added to it. i have poultry cell i can add as well. other threads mentioned giving a b-complex and maybe baby aspirin. does anyone have any ideas or possible solutions? thanks in advance.

hmm, quite puzzling. pictures and videos could help a lot.
check her crop. Is it hanging down or feel squishy?

Here’s pictures of her feet and hocks.

Here she is when we try to stand her up

Riboflavin (vitamin B 2 deficiency) can cause walking or sitting on the hocks, and may progress to lameness. I would give her 1/2 tablet of B complex daily, crushed in food. B12 is only cobalamin, while B complex has all the B vitamins including riboflavin. Could she have been injured? Do you see any swelling of her hock joints?

Started giving b complex yesterday. Her hocks look equal. Never inspected them closely before so not sure if swollen.
I few people have told me that this looks like Mareks but she was vaxxed as a chick and none of my other birds seem sick.

still giving vitamin and baby aspirin. no marked improvement. i poked around and found a bunch of assessment info....
her "head tracking" reflex is normal, vent reflex is normal, perching reflex is absent. i think she may have developed "kinky back" as a result of a fall of the roost bar. i can't find a ton of info on that here....
