You can try antibotics but I don't think it will help much. She probably has a bacteria infection, think of it more like a (and I'm not trying to be grose) yeast infection on women. Women don't take antibotics to cure it, liquid diet is what she needs right now to get the crop empty, lots of massaging as well, at least 20 minutes.. And no you don't want to give her vagasill. Lol....she's still a chicken......
