I would give her 2 drops daily directly in her beak. There are some poultry vitamins such as Rooster Booster Vitamins with Lactobacillus, that you can add to the water, and they also contain a probiotic.Thank you very much. I bought some Poly-vi-sol at the store. I Have her a couple drops today and added some to her water. Can you give too much? I'm trying to be cautious.
