Howdy! One of my chickens has been struggling for several days now. I have her separated and with me at almost all times. She is currently in my office now . I have been hand feeding her water and food/water mix. She cant hold her head up and freaks out by tucking it. She has lice, which I just treated. Her poop is very watery, smelly and yellow. She is fighting hard and seems to want to live. I need any advice, as she will need to be put down if she does not improve. She needs constant care and cant keep her head up on her own. Any advice?
