For little ones , I wrap in a wash cloth burrito.
I mix the medicine in with a little made up baby bird formula. If as an an example if the medication is 0.02 ml, I add it to the made up formula to make a total of 0.25 ml . I draw up a the meds first in the syringe then draw up the formula in the syringe, then sort of Rock it back and forth in the syringe . I hold the bird head upright, and give slowly at beak tip.
Having the meds thickened up a little with the formula helps reduce the chances of choke or aspiration.
If there are more than one medication due at the same time, I ask the vet if these medications can be put together in the same syringe with the little bit of formula. I try to keep the mix of meds and formula under 1 ml total for little birds. I use a 1 cc or tuberculin syringe.
For birds thst are a little larger like my GCC or bigger, who are trusting and tolerant. I have everything ready , I have them stand on a wash cloth, I put my left hand on their back , with thumb and pointer finger on each shoulder to hold them gently in place , head free. I offer the syringe ( 1 cc size it 3 cc size ) with the meds and made up baby bird formula at beak tip and give slowly.
Sometimes I will use applesauce in the syringe instead of formula. But I always keep baby bird formula on hand , ever since my clymadia crises a few years ago. Plus it's complete nutrition, easy to digest, has probiotics already in it , and most sick ones need a little calories boost anyway.
I have also used a tiny pinch of bread to soak up meds , if they will eat that .
I'm so glad you hit her in , and all the help she needs to get better! I hope all goes smoothly and she all fixed up soonest !
