We have lost 2 hens in last 2 months to this exact same illness. Now our 3rd is sick, she wobbles when tries to walk, wont really move, not eating or drinking. I am at a complete loss as to what is wrong. Any help is desperately needed!! I have given her electrolytes, syringe feed yogurt and water. No respiratory s/s of illness.
Try vitamin therapy. You can use PolyviSol baby vitamins without iron, or poultry vitamins mixed with water. Administer with a syringe a drop at a time, don't force it down her throat, just wet her beak and she will instinctively swallow. I have seen this as well. I find administering vitamins a couple of times a day for 2-3 days will help get them over whatever it is. They will seem weak and recovery will be slow, but mine do get better.
