12 days, what should I do if the right leg of Feng Xuan parrot chicks is left out?

Let's see if there are any injuries first. If there is no injury, it is calcium deficiency. You can go to a professional place that specializes in treating animals.

If calcium is deficient, use water-soluble calcium and water-soluble vitamins from Versailles. The dosage is generally 0.25g ~ 50m l of water-soluble calcium and 0. 125g ~ 50m l of water-soluble vitamin. Add this amount to the soaked millet and feed it, and there will be more sunshine.
