x2If possible, I would try to give a dose of benadryl if you have any. Give 1/2 of a 25 mg benadryl tablet if you vpcan get it down her throat. Looking at your picture, it really looks like her tongue has been stung or injured. She may be able to breathe okay through her nostrils. Is there any way to get her to a vet or animal ER right away. She could be fed and watered with a feeding tube or crop tube, until the swelling goes down.
I suspect she swallowed an insect that stung her. Childrens Benadryl as directed by Eggcessive will keep her trachea open unless the swelling presses too hard on the trachea closing it off completely. Watch her comb for darkening, a sign of lack of oxygen. At that point it might be best to put her down.
@Dgrif5 Where do you live, and do you have scorpions and/or fire ants, ground wasps?
