If your chicken is sick you should see a vet. Veterinarians are trained to recognize symptoms and diagnose and treat your animals.
A chicken will get sick if you don't give it food for days or let it outside. If a chicken is sick it will die a few days after. So always give them food everyday or leave them outside every night. You can tell that a chicken is sick when you see it. a sick chicken has dirty feathers. If it's already sick give the chicken an animal medicine from Lillia or Barley.
Chickens do stand out in the rain even when they have a dry coop a few feet away. Occasionally they will catch a chill and get sick just like people but for the most part, they just shake off and go about their business.
