Sorry that she is not doing any better. Mareks disease is in the environment, and fairly common. Hatchery chicks don't usually come with it, but they can get it in many homes if the virus is present in the environment from dust and dander. It can last up to 7 years in one's environment. Here are some examples of chicken slings or chairs to keep her upright and hopefully, cleaner. Keep her food and water within reach.
