I have a Rhode Island Red she is not eating and just stands in one spot fluffed up as if she is on the roost. Her droppings are a yellow color. I have no idea how old she is my neighbor gave her to me and she has been the light of our lives. we call her Thelma she has a sister and she is Louise. Thelma has been this way for three days. I used safe Guard goat wormer to worm her and milk thistle weed incase of Black head disease for the liver. Any Ideas?
