i have a sick hen.
Symptoms: heavy breathing, lethargic, disoriented and uncoordinated, but not making any noises. Comb is red, eyes clear.
i have no idea what it is or what i should do. any advice would be greatly appreciated.
Isolation is best. Most likely you will want to supplement her food intake. Chick starter fortified and some types contain antibiotics. Keep her warm and watered.
It can be difficult to find a vet that will see a chicken. The Veterinary Teaching Hospital at UT will see chickens. Dr. Jones or Dr. Greenacre will check out the bird without a refferal.
I've found these forums helpful for chicken health issues.
