I sometimes wonder if tests performed confuse the liver disease caused by Vibrio bacteria with fatty liver disease, which can happen to birds in moult condition for awhile or inactivity. Thioctic acid (an antioxidant) should be an ingredient included in poultry supplements to support and detox the liver. Choline is often added in diets, but not thioctic acid.Dr. Mason also reviewed pics of the other hen's odd liver that LH still has on her phone (she never deletes any of my messages, must be hundreds, lol) and he said it looked exactly like Spotty Liver Disease, that it is making a comeback now. Interesting, that's exactly what I originally felt it was myself.
