Update: Chicken still sick, can’t walk or stand. She can perch

My poor Pickles went to the vet, laid an egg, (I thought she was egg bound), she’s been getting around the clock care in quarantine, but she still can’t walk, she can perch on a dowel, but that’s it. She is eating at least one scrambled egg a day, not really drinking but if I string water over her beak she drinks. Her poops looked normal this morning, yesterday they were mixed, some normal, some watery. It’s been 6 days of this.

WTH??

This is her little set up. Any ideas?
