I have a black sexlink hen that is approximately 10 months old. She was started laying eggs on 23 September. She layed 56 days straight, missed 1 day, layed 10 days, missed 1 day, layed 2 days, missed 2 days, layed 2 days, missed 1 day, layed 1 day, missed 3 days, layed 1 day, then stopped laying altogether on 12 December. She got lethargic and was not looking well at all. I did a little research of course and could only start making guesses as I could see no other symptoms. None of the others were showing any signs of problems. I isolated her in another pen and eventually gave her ACV in water. I was trying to address a possible sour crop at the time. Anyway, she started getting well and bounced right back. She began laying again on 6 January and layed eggs everyday again through 30 January. On 31 January she stopped laying and is again looking lethargic. This time it seems much worse and she is losing weight. There is no visual symptom. No coughing, sneezing, respiratory issues. No mites or lice have been seen. There is no evidence of blocked crop or anything. So now what? I am certain, that if I can't figure this out real soon, she is going to die. She looked tonight as if she could barely hold her head up. When I picked her up and checked her over...and set her back down, she never moved from the way I set her down. It was pathetically sad really. Does anyone have any ideas to help me figure this out?
(BTW, I have 11 chickens. She is the only one looking or acting sick.)
