One of my hens started losing feathers. I assumed she was moulting. It is getting pretty extreme. But having never had one moult before, I wasn't alarmed. But now she appears to be having some other symptoms. Such as not walking straight. She also seems a bit slow when it comes to going after scratch. She goes about scratching and eating. But something is definitely off. I've tried to find info about her symptoms. But nothing matches up. Can moulting make a chicken act so bad?
