Not sure what your question is. Do you maybe give the liquid wormer in the drinking water, and are not sure how to do it any other way? I have often dosed the liquid medicine straight down the throat, but it does work much better with 2 people. One to hold the bird and one to use the syringe. Once you know what the inside of the mouth and throat look like and where the esophagus is located it is pretty fast and easy. Pills can pretty much be dropped down the throat as well, they don't tend to cough them back out like cats and dogs will. My peacocks are very easy to medicate, my guineas on the other hand are biters, so they are harder to deal with. We recently had a Barred Rock hen adopt us and our barn, she is my neighbors chicken but has decided she likes our place better, she is in my barn 24/7 and she had the nastiest case of diarrhea you'd ever want to see. We dosed her for 5 days with liquid safeguard for worms, general cure(metro) for blackhead, and bird sulfa pills (smz/tmp) for e-coli and any number of other secondary infections just to try and make sure she didn't infect our other birds with anything. The diarrhea is much improved and medicating was not hard at all.
