I have 7 new chicks (first time chick owner), and all are acting completely fine, except one, and I'm worried. Here are her symptoms: - wobbly; if she falls on her back/side she has trouble getting back up - will stand next to the food/water but won't eat or drink - chirps a lot - likes to hide in my hands; tries to hide under her sisters. When she hides in my hands she calms down a lot and stops chirping. I've given them antibiotics in their water, and I gave her some vitamin D/riboflavin supplement just a bit ago. Is she sick? Just unfortunate enough to be at the bottom of the pecking order? What do I do? I'm very worried.
