When Meloxicam is given to the avian patient it is usually given *twice* a day.
Marbofloxacin is a fluoroquinolone and should not be taken with calcium.

@jendarwin , the Marbo and the meloxicam are more important than the calcium, so get started on those right away.
Did the vet say to give the Marbo and meloxicam twice a day?
Are you giving the calcium once or twice a day?
You should talk to your vet, but I read that the Marbofloxacin should not be given at the same time as calcium. Are you comfortable giving injections? If so you could give calcium injections instead of calcium pills.
