Great news!! My baby chick is doing so much better. She is now standing on her own, walking and drinking. She still walks in circles when she walks and keeps her head bent slightly. Sometimes she loses her balance and catches herself with her wing. Her rattling sound when she breathes has ceased completely and she is pooping like crazy. Her poops are pretty liquid but she did go almost 24 hours on a liquid diet so that is to be expected. She is making great strides. If she keeps going like this, I am hoping for a full improvement in 2-3 days and maybe a reintroduction to her sisters. She is significantly smaller than they are now (its amazing how quickly they grow in just a few days).
I am keeping her on the vitamin water and save a chick combos and have started reintroducing solid chick starter feed soggy with vitamin water. To those who are struggling with this now, keep your chin up. If you are vigilant in the treatment they can pull through. I swear this poor babe looked like she was a gonner 24 hours ago. Completely unable to walk or stand. Now, she is making good strides. To those that have lost their poor little chicks, I am truly sorry.
Based on the symptoms, I feel pretty confident saying wry neck (ducking head back, walking in circles, head cocked to one side "stargazing", unable to eat/drink, and no other chicks showing any symptoms. She was the smallest of the six, so I am thinking one of two things happened: either she was being prevented from eating/drinking by her bigger flock mates or she came to me Saturday with a problem already developing.
Good luck to anyone trying to heal their baby from this terrible thing.
