Good advice from azygous. Hold fluids up to beak often. Mushy wet chicken feed and egg is good as well once she is drinking. A hurt leg or imbalance can limit what she has been eating and drinking. Watch out for any bullying. Make sure that she can see or visit with the others for company, if she is separated. Hopefully, it just an injury or heat exhaustion and not something like Mareks. That can strike at this young age. As for vitamins, human B complex or super b complex tablets 1/2 tablet crushed in food or a bit of water daily is good for deficiencies and leg problems.
