This morning my Barred Rock came out of the coop and proceeded to lay a green, watery poop. I kind of freaked out because I had just been researching chicken diseases and remembered reading about green, watery poops. I ran back up to the house to find the chart I'd been reading. You can see it here. http://edis.ifas.ufl.edu/ps044 The Barred Rock also has clear fluid coming out of her nostrils and last night had labored breathing. I was worried it might be Newcastle and asked my fiance to come with me to check the birds out. He said that since the Rock doesn't seem to feel badly (she's pretty perky, despite the temperature) and since it's been nearly 100 degrees all week, she might just be showing symptoms of heat stress. I've tried to find a good page that indicates what those symptoms might be. Does anyone know if clear fluid from the nostrils and green, watery poop could be due to heat?
