Before running to antibiotics I would first do a thorough exam. Here's a link to help you begin making observations and things to look for.
If she was spitting up fluids the first thing I would check is her crop. Then make as many observations as you can to narrow down what is causing the symptoms.
Note on penicillin: Antibiotics are only good for bacterial infections not viral. Many bacteria are resistant to several antibiotics and more so with penicillin (and similar) because of over usage and incorrect usage. So it helps to know what type of illness your treating so you can give the correct antibiotic for the correct illness and in the correct dosage.
I'm so sorry for your loss. Seems so sudden. Did you check to see if she was egg bound?
I hope you can report back on anything you can find that may be helpful to someone else that has a similar experience.
My only other thought for a quick death (other than egg bound or internal laying) is possibly heart trouble. But who knows she may have been ill longer and hiding her symptoms well.
