I found one of my bantams (2 or 3 mos old) on the floor of the coop on Sunday. It's like she's sort of paralyzed, but she can walk a little but clumsy and wobbly. Something is wrong with her neck. Its limber and crooked. She can't hold it up too long. There is a protrusion on the left side of her neck and it feels like her neckbone/spine protruding. I've been searching all over the internet and It could be so many things. She is eating and drinking some. Her diet was chick grower. I am now giving her probiotics and electrolytes in her water and medicated chick starter mixed with water. Should I be giving antibiotics or something else. Please help!
