My 5 wk old girl had yellow, very watery poop and was so lethargic I thought she was going to die. She was revived after electrolytes and eggs and began pooping and acting normally for the rest of the day and all of the next day. But when I went out for the first of the morning check, she is once again lethargic and had yellow watery poop. I have been using a heating pad cave, no lamp. I'm wondering if they are sleeping on top of the cave and she isn't getting warm enough. Would that alone cause her symptoms?
