Okay she is definitely NOT is a good way and that looks much more like blunt trauma than frostbite. You should take action right away.
The way her comb is flopped over might indicate severe dehydration. I'm guessing she hurt her toe stumbling onto/off of something? That comb is pretty small, too. So do you think she's 4-5 months old?
See the way she's puffed up? She's very uncomfortable (possibly just really cold, but possibly something more). Possibly in a lot of pain (hence being feisty).
I'd definitely recommend quarantine in a cool structure that is draft free (like the garage) for the time being. An open dog crate, or even a big cardboard box will do. She's obviously not going to run/fly away at this point. Don't worry about a heat lamp for now.
Try to dip the tip of her beak in a spoonful of water. Does she drink? If she's offered feed, will she eat?
If she is dehydrated I'd recommend hand watering with an electrolyte-enhanced water: save-a-chick or I've had great results with Rooster Booster. But even pedialyte will work in a pinch. Also poultry Nutri-Drench is a great liquid "food" booster... I've never found a chicken that liked it undiluted, but diluted I have yet to meet a chicken that didn't like it.
If she won't eat feed we need to come up with another choice. But one step at a time.
You'll have to watch her closely and provide more information to make progress. Please read the following post guidelines and then offer the information you have not provided already:

What we need to do is figure out if what's ailing her is communicable or not. If she might have a communicable illness you don't want her near the rest of the flock. You'll need to monitor her behavior as well as monitor the rest of the flock to see if they begin exhibiting any of the same symptoms.
Please let us know what you find out!
