Giving Baytril orally does not have as good an effect as injections.. injecting is really the best way to give it.

Are you uncomfortable giving the injections by yourself? Does the snake react negatively for the injections? I have (unfortunately) given many shots to snakes and have had no trouble giving them myself.. this includes my 21lb dumerils boa.

If you do not feel comfortable doing it on your own though, don't push yourself. Try and see if you can't find someone to help you.
