No, if you decide to give her the enrofloxacin you need to give that orally or not at all. It is very bitter and most birds will not eat or drink anything that has enrofloxacin in it.It's a good easy way for me to get some antibiotic into her if I mix it with her mash.
As I said before, I don't think it will harm her.just continue with the Miconazole?
