1) What type of bird , age and weight (does the chicken seem or feel lighter or thinner than the others.). She is a barred rock, I don't know her age, but her weight is normal, 5 pounds. She seems a little thinner than the other chickens, but the weight matches the others. 2) What is the behavior, exactly. She is very lethargic, not moving and doesn't seem to wanna walk. She is drooling, spitting, gaping, bubbles around the eyes. 3) How long has the bird been exhibiting symptoms? About a year, but it has gotten worse over the past months. 4) Are other birds exhibiting the same symptoms? No, the other birds are fine. 5) Is there any bleeding, injury, broken bones or other sign of trauma. She does have a leg problem, it was stepped on by a horse and is twisted, making her walk funny. 6) What happened, if anything that you know of, that may have caused the situation. I think the disease is MG, all the symptoms match - http://poultrykeeper.com/chickens/health/mycoplasma-gallisepticum.html 7) What has the bird been eating and drinking, if at all. She is eating layer pellet, and is drinking water with apple cider vinegar as a supplement, and Vet RX as well. 8) How does the poop look? Normal? Bloody? Runny? etc. Normal. 9) What has been the treatment you have administered so far? Nothing really, just vet RX. 10 ) What is your intent as far as treatment? For example, do you want to treat completely yourself, or do you need help in stabilizing the bird til you can get to a vet? I can do it myself, I was hoping on getting a powder, but its very expensive, so I might have to get a injectable. 11) Describe the housing/bedding in use. 4 x 3 coop with wood shavings. What do you all think?
