My daughter's beloved Bantam, Pink Feet, is sick and I need your help. She is 4 years old and has, within the last week, started exhibiting symptoms of illness. She is a little larger than a robin, does not have diarrhea, but is walking and moving very slowly with her feathers puffed out and her wings held slightly down. Any suggestions are greatly appreciated! No other hens are ill at this time. She also does not seem interested in eating some of her favorite foods.
