I have a chicken who looks just like that! its so sad because she is my oldest and dearest hen Ginger. she is about three years old. she hasnt been laying for about a year now and was hale and hearty that whole time so I wasnt too worried about that (tho she was previously a faithful egg a day summer or winter). any way she has been growing slightly more and more lethargic for the past month or more, comb is droopy and pale. she is losing weight. the thing is, last summer i had a chicken get sick and die over a period of about 2 weeks. she was so weak in the end she couldnt move, I was giving her water and B12 with an eyedropper, checked her crop, warm soaks, checked her vent the whole nine yards. in the end she was just skin and bones. Two weeks ago I had a barred rock who had just hatched three chicks (sat on 12) and over the course of 2 DAYS she became lethargic and just up and died! what is happening? are these three things related? do chickens get worms or any other sort of wasting disease? PS no signs of respiratory illness in any of them. Please help!
