Whenever one of my girls seems a bit "off", I supplement her diet by feeding her some foods that are high in vitamins A, K & E , especially vit. A. She might have a nutrient deficiency, and vitamin A is one of the most important vitamins for a chickens overall health.
Some foods high in vit. A are: broccoli, butternut squash, carrots, sweet potatoes, pumpkin, mangoes & tomato juice. Spinach, peppers & alfalfa leaves for K, and sweet potatoes & broccoli for E, which helps boost the immune system.
If you have any of these veggies, boil them up until they are soft & chop them into bite-size pieces or mash them with a fork.
I'd add some Sav-A-Chik or other vitamin/elecrolyte solution to her water until you can get some amprolium, or give her a drop of Poly-vis-ol from Enfamil (no iron formula) a day for a few days. 1 drop for chicks, 2 for smaller hens, 3 for standards.
When you have her on amprolium, do not add anything else to the water.
