She is a little over a year old, fine up until a couple of days ago,, she started acting lethargic, inactive and now she is not moving at all,, she is not eating or drinking. I have been giving her liquids with a syringe. Her eyes are always closed and her head in laying on her back. She has labored and shallow breathing,, I have felt her neck and breast and her crop is not engorged. Her neck is in an "S" shape and if I try to move her head or neck she started to flop around and her head swings all over. There are no mites and all of my other hens are fine. We did have a black snake in the coop, which is now gone. They are free range during the day and closed up at night. The neighbor has found a copperhead or two on his property and we thought maybe a snake bite. We also have an 80lb dog that gets excited and starts running crazy through the yard and thought he may have accidently ran her over, breaking something. Thoughts??
