My australorp cannot walk as of last year when she had mites in her legs, but she got treated. Today she won't drink. It's very hot where I am and she is very overheated- so I'm worried. When I got home, I picked her up to chill her off, but she spit out some saliva. She's not eating her usual food, just bread. As I said, she refuses to drink, so I hand gave her some water. Does anyone know why? Thanks.
