Hello I have a hen that’s been acting weird.I got home for school yesterday and she was panting and breathing really hard and has one of her eyes shut and won’t open it,when she does it is really watery.She won’t eat anything but will drink.All my research shows that it’s a respiratory infection?If so is it treatable?What can I give to treat her?Iv already spread vetrx under her wings and on her head.I also gave her 3 drops into the mouth.
