Update on sick chicken

So a couple days ago I made a post about my chicken being possibly sick but I wasn’t sure. So far she’s still alive and she’s pretty alert. She eats mushes poultry feed and drinks water, but she can’t walk. She also has a tough time trying to balance, like I notice we have to put her in a certain position for her to stay upright. When she tries to adjust herself, she uses her beak to kind of drag herself, if that makes sense? She still goes to the bathroom but she’s always sleepy. I don’t know why she can’t walk yet, I felt her legs and they are still warm. When we try to get her to walk she just cries and tips foward. It breaks my heart seeing her like this.

Can somebody please help me find out what’s wrong with her? I’m trying to help her the best I can but I’m not sure how else to help her. My parents don’t know either and they kind of gave up on her but I haven’t. Please help! Ask me any questions and I’ll answer to the best of my ability.
