My 9 week old hen Violet has not walked in a week and a half. Two days before she stopped walking the other girls had pecked at her feet, one foot worse than the other. We put some blue food coloring on the red areas to stop the pecking. The following day she was limping, then the next day she had completely stopped walking. I checked her feet and legs for anything out of the ordinary but there is nothing wrong with her. Comb is starting to get slightly pail compared to what is was and she has lost tons of weight. It looks like she has a scab (dark colored due to the food coloring) on her foot where they had pecked at her. I put apple cider vinegar in the water and cinnamon, garlic & oregano in the food to help boost her immune system. I have no idea what is wrong with her and would really appreciate some help in figuring it out.
