if she still dosent eat, you may want to force feed her by pressing either side of her mouth, forcing it open and then poring liquid food in
Please do not pour liquid feed into the mouth of a chicken. It will choke her, she can also aspirate liquid/feed into the lungs and get an infection.
A better solution IF she needs to be "force fed" is to either syringe or tube feed directly into the crop. The following links can help walk you through that.

@Animalsforever1234 if you photos of the wounds that may be helpful. FlyStrike can be difficult to heal, especially if there are still maggots or the maggots have gone deep into the body cavity.
Inspect the wound again to see if there are more maggots or if the wound has become infected. She may need antibiotics.
Keep her hydrated and try offering a wet mash of food. Nutri-Drench along with some scrambled egg would be good to try as well like @llombardo suggested.
