Yellow foamy droppings, inreased thirst, red face

[melslp13]

HI all, I have a almost 2 year old blue ameraucana experiencing some sort of distress. She was fine yesterday but has not lain today, and when we went out to do chores, we found her by the waterer drinking copious amounts, with a wet vent area and yellow foamy slime on the ground under her and stuck to her feathers. She's in isolation now in a darkened, cooler area. It's only 70 today, so I can't think she's overheated. She's not waddling or acting uncomfortable or fluffed up. Just drinking and drinking and drinking. Any thoughts? Please advise.
