Poor girl, that sounds like she's having a bad time.
As always, if a vet visit is possible/reasonable: do that before taking any advice I have to give!
Honey is good for quick calories if she's not eating well - make sure to give a poultry vitamin supplement also though (actually, do this even if she's eating normally, it'll help her recover).
I've noticed turkey faces can swell up pretty much any time there's a sinus/respiratory issue. After an injury like that, I'd probably see if the swelling was getting better or worse for a day or two before changing anything. If it's not getting better after a few days, there might be a secondary infection setting in while her immune system is compromised. If that's the case, consider giving an antibiotic.
