URGENT QUESTION!!!

I have a few hens that live in my backyard in a little coop. One of them got trapped out in the rain during a storm the other night and got drenched. We found her the next morning and brought her in. She wasn’t able to walk or hold herself up at all really. We used a blow dryer (made sure it wasn’t too hot or too cold) to dry her off. Then we kept her separated and inside, giving her lots of fruits, veggies, pellets, and water. It’s been about two days and she started clucking again, but her legs won’t work. We’ve tried to make her stand, but she refuses to hold herself up on them. She sits on her hind end with her feet not even bothering to hold her up or keep her balance. We don’t have money to take her to the vet unfortunately, so any advice is GREATLY appreciated!!!
