Please help! Labored breathing, puffed up after predator attack

You have done everything I would have done. It might be in shock, and after some rest and electrolytes it may be alright. Chicks can be pretty delicate creatures, so only time will tell. If there are internal injuries, that could really complicate her recovery. Make sure that her heat lamp is around 80 degrees on the floor, but higher could make her pant more (unless she is only a week or so old.)
Feel of her body to make sure that she doesn't have air under the skin from a leaking air sac due to injury. She may not have that, but is just looking puffed up. Crops can become slow emptying after illness or injury. Liquids are the most important now, but putting some water into her feed, and a little raw or chopped egg would be good for her. Make sure that she doesn't have pasty butt, so just clean it off if you notice that. How old is she exactly? Here is some info on a leaking air sac:

Sorry about losing Louie. With attacks by other animals, we just never know if they will survive or not. I've have several injured, and the one that looked the least injured was the one who died. I had a 2 week old chick with a large leaking air sac who I was able to save by deflating it several times, only to get through the fence and be picked off by one of the dogs a month later.
