I posted before about my chick (she was 10 days old then) who had no energy and was sleeping a lot. I didn't really get many responses. Since then, she started to have weakness in her neck and her head started to roll to one side. She could barely eat or drink, she was so weak. My DH went to the feed store and the old-timers there felt it was a respiratory infection and suggested tetracycline hydrochloride, which we've been adding to their water every since. She was making improvements in her head not rolling so much and her energy increasing (less sleeping) until this afternoon. Now she seems kind of lopsided when she walks around and seems to have lost her depth perception. When I put my hand to one side of her she seems to not see it until it is very close to her but on the other side she sees my hand right away (reacts by running away). Her head seems to be rolling to the side again and I noticed when she was sleeping her head bobbing up and down as if she was pecking at something. This behavior when she's sleeping seemed to stop and start but almost in a pattern, as if it might be neurological. I'm very worried about her... we've been babying her for quite a while. She is only with one other chick who is doing fantastic. She seemed to be in perfect health the day we brought her home (1 day old) and for the first week of her life. Any ideas or help would be great. 5Leepy!
