Yes, I would continue the antibiotic. If you have bad smell, it's needed.
The most common dose of enrofloxacin is 10mg/kg (I've seen it as high as 15mg/kg in a few places), twice a day. Since your medication is a 20% solution, that should be 200mg/ml. So if your bird is 6 lbs, that would be .14 ml twice a day (for 10mg/kg dose), orally. Depending on the size of your 'drop' you may be close to that, but need to do it every 12 hours.
This thread has the math and dosing info:
